MMO & MMORPG Terms Dictionary / Glossary

MMORPGs have exploded in popularity, but for newcomers, the sheer volume of jargon thrown around by seasoned players can feel like learning a second language. This guide breaks down the most common MMO abbreviations, acronyms, and slang into plain English, so you can jump into any conversation or any game without missing a beat. Share it with friends who are just getting started, and before long you’ll be speaking fluent MMO.

1337 A numerical cipher for the word “elite,” pronounced “leet.” Born out of hacker culture in the 1980s, 1337-speak substitutes letters with visually similar numbers and symbols. Over time, fragments of it seeped into mainstream internet culture — using a “z” in place of an “s” (as in “kidz”) is one surviving example. Today it’s most commonly encountered in online gaming communities.

A

AAA MMORPG / MMO “Triple-A” has no formal industry definition, but it’s broadly used to describe games backed by large development budgets and extensive marketing campaigns — the blockbusters of the gaming world.

AE / AOE Area of Effect. Refers to any spell or ability that damages or impacts all targets within a defined radius. Classic examples include fireballs and smoke grenades. AOE and AE are used interchangeably.

Add An additional enemy that joins a fight mid-encounter, usually uninvited. Adds are a common source of wipes — a boss fight that seems manageable can turn catastrophic the moment a patrol wanders into the middle of it. “Watch for adds” is one of the most universally heard callouts in raiding.

AFK Away From Keyboard. A heads-up that the player has stepped away from their computer and won’t be responding.

AH Auction House. The in-game player-driven marketplace found in most MMORPGs, where players list items for sale and others bid or buy outright. The AH is the economic backbone of most game economies and a destination in its own right for crafters, traders, and bargain hunters alike.

Aggro As a verb, aggro describes a mob that has detected a player and begun actively pursuing them. As a noun, it refers to the accumulated threat a player generates with a mob. Smart group play involves the tank absorbing as much aggro as possible to protect healers and other vulnerable teammates.

Alt Short for “alternate character.” A secondary character that a player runs alongside their main. The line between alt and main can blur over time — some alts eventually surpass the original in time investment and level.

AO Abbreviation for Anarchy Online, a science-fiction MMORPG.

Attribute Core character statistics such as Strength, Constitution, Dexterity, and Intelligence that define a character’s capabilities and combat performance.

B

BAM Stands for “Big Ass Monster.” Typically applied to world bosses or any unusually large and dangerous enemy encountered in the open world.

BG Battleground. An instanced, structured PvP zone where two teams compete toward a defined objective — capturing flags, holding points, or escorting payloads. Battlegrounds offer a more organized alternative to open-world PvP, with balanced team sizes and clear win conditions.

Bind In games where players respawn at a designated location after death, the act of setting that location is called a bind. The saved spot itself is called a bind point or bind spot.

Bio Short for “biological” — a polite way of saying someone needs a bathroom break.

BiS Best in Slot. Refers to the single most powerful piece of gear available for a specific equipment slot on a character.

BoE Bind on Equip. An item classification made popular by World of Warcraft. A BoE item can be freely traded until the moment a player equips it, at which point it becomes permanently bound to that character.

BoP Bind on Pickup. Another World of Warcraft term. A BoP item becomes permanently bound to the player the instant it’s looted, making it untradeable. BoP drops are a frequent source of group drama.

Bot An unauthorized automation program that controls a character without player input, usually to farm experience or currency around the clock. Botting violates the terms of service in virtually every MMO and is actively monitored by Game Masters. Accounts caught botting are typically suspended or permanently banned.

BRB “Be right back.”

BRT “Be right there.”

BTW “By the way.”

Buff A temporary enhancement applied to a character that boosts a stat or combat ability. Buffs can come from spells, items, or environmental effects.

C

Camp / Camping The act of stationing yourself in a specific location to repeatedly kill a particular mob or wait for a rare spawn to appear.

Carry When a high-skilled or high-level player essentially does the heavy lifting to pull a weaker player through difficult content. Being carried means you made it through an encounter largely on someone else’s efforts. Offering or requesting carries has become a cottage industry in many MMOs, with some players charging in-game currency for the service.

Class A character archetype that determines a player’s available abilities and role in combat. Common archetypes include warrior, healer, rogue, and mage. Most classes fall into one of five broad roles: melee damage, ranged damage, healing, crowd control, or support.

Cleric The archetypal healing class in Dungeons & Dragons-style fantasy games.

CoH Abbreviation for City of Heroes, a superhero-themed MMORPG developed by NCsoft.

Corpse In games with a death penalty, a player’s corpse marks the spot where they died, sometimes retaining their items and currency. The corpse decays after a set amount of time and serves as both a memorial and a retrieval mission.

Corpse Run The often-dangerous journey back to retrieve your corpse after dying. Since players tend to die in hazardous locations, the return trip can be just as lethal as the first.

Crafting A category of in-game skills that allows players to create weapons, armor, consumables, and other items from raw materials gathered in the world.

Crit Short for critical hit. Landing a crit dramatically increases the damage dealt — typically starting at 150% of normal damage and scaling higher with the right talents and buffs.

Crowd Control (CC) A category of abilities designed to temporarily incapacitate enemies — through paralysis, sleep, fear, or stuns — giving the group time to manage a dangerous situation. Essential in fights against multiple enemies.

D

DAoC Abbreviation for Dark Age of Camelot, a fantasy MMORPG notable for its large-scale Realm vs. Realm PvP.

Dailies Repeatable quests that reset every 24 hours, typically tied to endgame progression systems like reputation grinding or resource collection. Logging in and completing your dailies is a ritual for dedicated players, though the repetition can wear thin over time.

DD Direct Damage. Any spell or ability that deals immediate damage to a target from range. The firebolt is the quintessential DD.

Debuff The counterpart to a buff. A debuff is a negative spell cast on an enemy that reduces their stats or combat effectiveness.

Dispel / Cleanse Abilities that remove negative effects from allies or strip beneficial buffs from enemies. A well-timed dispel can be the difference between a clean kill and a wipe — removing a healer’s silence or cleansing a debilitating poison at the right moment is one of the more underappreciated skills in group play.

Dex Dexterity. A critical stat for rogues and archers, Dex typically governs attack speed, dodge rate, and sometimes defense.

Dirt Nap Slang for being dead, referring to the way most characters fall face-down on the ground when killed.

DKP Dragon Kill Points. An organized point system used by guilds to track member contributions during raids and distribute loot equitably based on participation.

DoT Damage over Time. A class of spells that deals sustained damage across multiple ticks rather than a single burst. DoT spells often deal more total damage than their direct-damage counterparts.

DPS Damage per Second. A metric used to evaluate how much damage a weapon, ability, or character deals on average over time.

Druid A hybrid class in fantasy RPGs that blends healing, support, and combat abilities, drawing power from nature magic.

E

Eating Grass Slang for dead, based on the visual of fallen characters lying face-down on the ground.

Enrage Timer A hard time limit built into boss encounters. If the group fails to defeat the boss within the allotted time, it enters an enrage state — dealing massively increased damage that wipes the group almost instantly. Enrage timers exist to prevent low-damage groups from slowly attriting their way through content they’re not yet geared for.

Epics High-tier gear that is both powerful and rare, typically found at the end of the most challenging dungeons and with low drop rates. Epics are often only surpassed by Legendary-quality items in games that include that tier.

EQ Abbreviation for EverQuest, one of the foundational MMORPGs of the genre, originally released in 1999.

Experience (XP) Points accumulated by completing quests, killing enemies, or discovering new areas. Accumulating enough experience causes a character to level up, growing stronger in the process.

Exploit Taking advantage of an unintended bug or mechanical oversight to gain an unfair advantage — clipping through geometry to skip a boss, duplicating items, or abusing a broken ability. Exploiting typically violates a game’s terms of service, and developers usually patch exploits quickly once discovered, sometimes rolling back the gains of those who used them.

F

Farm / Farming The practice of repeatedly killing the same enemy or running the same content to accumulate currency, materials, or specific items.

F2P Free to Play. Describes a game model where no initial purchase is required to access the game, though optional purchases may exist within it.

F2W Free to Win. Used interchangeably with F2P, emphasizing that the game can be fully enjoyed without spending money.

FTL “For the Lose.” Used to highlight a choice or circumstance that led to failure. Example: “Going AFK during the final boss FTL.”

FTW “For the Win.” Used to credit a specific action or ability with securing victory. Example: “Stun FTW!” meaning the stun was the deciding factor.

G

Gank To be ganked means to be ambushed and killed by an overwhelming force — either a large group of players in a PvP environment or a swarm of high-level NPCs. The term carries a strong implication of unfair advantage, whether through numbers, level disparity, or coordination. “I got ganked in the open world” is a common complaint.

Gacha A monetization mechanic borrowed from Japanese capsule-toy vending machines, where players spend premium currency for a randomized chance at rare characters, gear, or cosmetics. Gacha systems are ubiquitous in mobile MMOs and have become one of the most debated monetization practices in gaming, owing to their resemblance to gambling mechanics.

Gear Score / Item Level (ilvl) A numerical rating that summarizes the overall quality of a character’s equipped gear. Gear score is frequently used as a gatekeeping tool — players often require a minimum ilvl before accepting others into groups, for better or worse. It’s a convenient shorthand for preparedness, though it doesn’t always tell the full story of a player’s skill.

GM Game Master. An employee of the game’s developer who operates an in-game character to monitor the world, assist players, and enforce the game’s rules. GMs have sweeping administrative powers and can issue warnings, suspensions, or permanent bans for serious violations.

Griefer A player whose primary goal is to make other players miserable — camping low-level characters, disrupting events, or otherwise ruining the experience for others with no personal gain beyond the satisfaction of causing frustration. While all griefers are often PKers, not all PKers are griefers.

Guilds Organized, semi-permanent groups of players who band together for social support, coordinated raiding, and shared goals. Forming a guild typically requires a notable investment of in-game currency.

GTG Shorthand for either “good to go” or “got to go” — context is everything, as confusing the two can cause real miscommunication mid-raid.

Grind The repetitive, often tedious process of performing the same actions over and over to make progress — leveling through low-content zones, farming reputation, or running the same dungeon for the hundredth time chasing a drop. Distinct from farming in that grind carries a heavier negative connotation; it’s the part of an MMO that tests your patience as much as your skill.

H

Heal Either a restorative ability that replenishes a character’s health, or an urgent call for help when a player shouts “Heal me!” as their health bar approaches zero.

Hardcore / Casual Two broad player archetypes defined by time investment and intensity. Hardcore players dedicate significant hours to mastering endgame content, optimizing builds, and progressing through the most challenging material. Casual players engage with the game at a lighter pace, focusing on enjoyment over optimization. Most players fall somewhere in between, and the distinction is often used — sometimes unfairly — as a social dividing line within communities.

Health (HP) The primary life stat of a character, also known as hit points. When health reaches zero, the character dies.

I

IAP In-App Purchase. Refers to microtransactions within mobile games — usually cosmetics, currency, or convenience items bought with real money.

IMHO “In my humble opinion.”

IIRC “If I recall correctly.”

INC Incoming. A warning shouted when a mob has been pulled and is heading toward the group, giving teammates time to prepare.

Interrupt An ability that cancels an enemy’s ongoing cast before it completes. Interrupting is a critical skill in endgame content — many boss abilities hit hard enough to wipe the group if they go off unchecked. Knowing which abilities to interrupt, and timing it correctly, separates competent players from great ones.

INC Incoming. Called out when a mob is heading toward the group, giving teammates a moment to prepare.

Instance A private copy of a dungeon created specifically for a group of players, isolated from the rest of the server. Instancing allows multiple groups to run the same content simultaneously without interfering with each other.

INT Intelligence. A primary stat for spellcasters that typically increases spell damage and expands the mana pool.

IRL “In real life.” Used to distinguish real-world context from in-game situations.

J

JK / j/k “Just kidding.” Commonly used across online platforms to clarify that a previous statement was made in jest.

Jumping Most MMOs let characters jump freely, sometimes to an unrealistic degree. Some games, like EverQuest, assigned a stamina cost to jumping to discourage spamming it.

K

K / KK / Kay All three mean “okay” and are used to acknowledge or confirm what someone has said.

Kite A combat technique where a player keeps an enemy at a safe distance while dealing damage, usually by applying a movement-slowing debuff and staying just out of reach. Often paired with DoT spells to whittle down the target over time.

KoS Kill on Sight. Describes a faction’s standing hostility toward a player character. If you grind enough kills against a faction, their NPCs may attack you on sight regardless of your actions.

KS Kill Steal. Taking the killing blow on a mob that another player was already fighting in order to claim the loot or experience reward. Most modern games have introduced systems to discourage this.

L

LD Link Dead. Describes a player who has been involuntarily disconnected from the server, usually due to lag or internet issues.

Leet Slang for “elite.” Derived from 1337-speak. Still used occasionally as a compliment or ironic boast.

LFG “Looking for group.” Broadcast in chat when a player wants to join a party for a dungeon, quest, or raid.

LFM “Looking for more.” Used once a group is partially formed and still needs additional members.

LFT “Looking for team.”

LMAO “Laughing my ass off.”

LOL “Laughing out loud.”

LOM “Low on mana.” A heads-up from a caster that they’re running low and won’t be able to maintain their usual output of spells for long.

LoS Line of Sight. Most ranged abilities require an unobstructed path between the caster and the target. Walls, pillars, and terrain features can break LoS and interrupt spells.

Loot Items and currency dropped by defeated enemies.

M

Medding Originally from EverQuest, where casters had to meditate to recover mana. Telling your group “I need to med” meant asking them to hold off on pulling until your mana was restored.

Meta Short for “metagame.” Refers to the current consensus on the most effective strategies, class builds, or compositions in the game — the optimal way to play given the current patch. The meta shifts constantly as developers balance the game and the player community discovers new techniques. Playing “off-meta” means deliberately choosing a less optimal approach, for personal preference or as a challenge.

Mez Short for mesmerize. A crowd control ability that temporarily freezes or stuns a target. Mez falls under the broader CC umbrella.

Min-Maxing The practice of optimizing a character’s build to extract maximum statistical performance — carefully planning every skill, stat allocation, and item choice to achieve the theoretically strongest version of that character.

MMO Massively Multiplayer Online. A genre of online games involving large shared worlds. Unlike MMORPGs, not all MMOs include traditional RPG progression.

MMORPG Massively Multiplayer Online Role-Playing Game. An MMO with RPG elements including character progression, classes, and story-driven quests.

Mob An AI-controlled enemy. The term dates back to the MUD era, where “mobile” distinguished patrolling monsters from stationary ones.

Mod Short for modification. As a noun, a mod is a third-party addition that alters or enhances the game experience. As a verb, to mod something is to apply that alteration.

MOO MUD Object Oriented. An evolution of MUDs that allowed users to build and contribute their own in-game objects and spaces.

MT Two distinct meanings depending on context. Most commonly, MT stands for Main Tank — the primary tank in a raid or group, responsible for holding aggro on the boss and positioning it for the rest of the team. It also stands for Mistell, describing a message accidentally sent to the wrong chat channel or recipient — a common mishap that occasionally leaks embarrassing information into guild chat.

MUD Multi-User Dungeon (or Domain). The text-based online worlds that predate modern MMOs and laid the groundwork for the entire genre.

Mule A character created not for adventuring but purely for storage or auction house access. Mules free up inventory on main characters during long play sessions.

N

Nerf To reduce the power of an ability, item, or mechanic — typically because it was deemed too strong. “They nerfed my main again” is a perennial player complaint.

Newbie A player who is new to a game. Newbie is the gentler term; see also “noob.”

Ninja Looting / Ninjaing The act of grabbing loot that, by group agreement or game convention, you had no right to take. In World of Warcraft, this specifically means rolling Need on a bind-on-pickup item that isn’t an upgrade for your class. Players caught ninja looting are often blacklisted by the community.

Noob The derogatory version of “newbie.” Often applied to players who display ignorance of basic mechanics, whether they’re actually new or not.

NP “No problem.”

NPC Non-Player Character. Any character in the game world controlled by the game’s AI rather than a human player — quest givers, merchants, guards, and enemies all qualify.

Nuke A high-damage, single-target offensive spell. Mages typically carry the largest selection of nukes in any given game.

O

OMG “Oh my god.” An exclamation of surprise or disbelief.

OMW “On my way.”

One-Shot When a single hit or ability kills a player instantly, reducing them from full health to zero in one blow. Being one-shot is one of the most frustrating experiences in any MMO, and avoiding one-shot mechanics is a core part of boss fight strategy in most endgame content.

OOC Out of Character. Used to flag that the player is speaking as themselves rather than roleplaying as their character.

OOM “Out of mana.” A caster’s way of signaling they’ve exhausted their spellcasting resources and need time to recover.

OST Original Soundtrack. Refers to a game’s music. Games like Ragnarok Online, World of Warcraft, and ArcheAge are frequently cited for the quality of their OSTs.

OT Off Tank. The secondary tank in a group or raid, typically responsible for picking up additional enemies — known as adds — so the main tank can focus on the primary target. A strong OT can be the difference between a controlled fight and total chaos.

Ownz / Pwnz To dominate or decisively defeat an opponent. “Pwn” is widely believed to have originated as a typo — the “p” and “o” keys are adjacent on a QWERTY keyboard — that stuck around and took on a life of its own.

P

Pat Short for patrol. A mob on a patrol follows a fixed path through an area. Experienced players learn to time their pulls around patrol routes to avoid accidental aggro.

P2W Pay to Win. Describes a game model where spending real money grants a meaningful competitive advantage — stronger gear, exclusive abilities, or resources unavailable to free players. P2W is one of the most contentious topics in online gaming, and a game being labeled P2W is often enough to drive away large portions of its playerbase.

PB / PBAOE Point Blank (Area of Effect). Spells that originate from the caster and affect everything in a surrounding radius. Effective but risky, since they require the caster to be in close proximity to enemies.

PC Player Character. Any character directly controlled by a human player.

PK / PKer Player Kill / Player Killer. A PKer is a player whose primary focus is killing other players, whether in designated PvP zones or through open-world aggression.

Port Short for teleport. Used both as a noun (“can I get a port?”) and a verb (“can you port me to the city?”).

Power Level When a high-level player assists a lower-level one in gaining experience rapidly — often by pulling large groups of enemies. Many games include safeguards that reduce or eliminate the benefit of power leveling.

Proc Short for “programmed random occurrence.” A proc is a bonus effect — extra damage, a heal, a buff — that triggers randomly when an item is used or a hit lands.

Prog Short for progress. Refers to how far a group has advanced through a difficult raid encounter. “What’s your prog on the final boss?” is a common question in endgame circles.

PuG Pick-Up Group. A party assembled ad hoc from available players, rather than an organized guild group. PuG experiences range from surprisingly smooth to legendarily chaotic.

Pull The controlled act of drawing one or more enemies back to the group’s position, giving the team home-field advantage rather than fighting in an open, spawn-heavy area.

PvE Player versus Environment. Any content where players fight AI-controlled enemies rather than each other.

PvP Player versus Player. Any content or zone where players can directly fight one another.

Q

Quest A task assigned by an NPC that rewards experience, items, or currency upon completion. Called “missions” in some games.

QQ A symbol meant to represent a pair of crying eyes. Used dismissively toward players who complain. “QQ more, noob” is a classic response to in-game whining.

QWERTY The standard keyboard layout used across most of the world, named after its first six keys.

R

Race The player’s choice of species or ethnicity for their character. Fantasy MMORPGs typically offer options like Elves, Trolls, and Orcs, each with distinct bonuses or aesthetics.

Raid A large-scale group endeavor — often requiring ten to forty or more players — centered on tackling powerful bosses and earning high-tier loot. Raids are the pinnacle of PvE content in most MMORPGs.

Regen Short for regeneration. Refers to the passive recovery of health, mana, or other resources over time. Also a common spell effect.

Rekt Slang for “wrecked.” Used when someone is thoroughly defeated or embarrassed. “You got absolutely rekt.”

Respec At certain milestones, some games allow players to reset and reallocate their character’s skills and abilities from the ground up. Short for “respecialization.”

Rez Short for resurrection. An ability that revives a recently deceased player, typically available only to healer classes. Getting a rez spares the group a lengthy corpse run.

ROFL “Rolling on the floor laughing.” A step beyond LOL, used for something genuinely hilarious.

Rogue A nimble, stealth-based class archetype that prioritizes speed and precision over brute strength or magic. Known by many names across different games — thief, assassin, agent — but the core fantasy remains the same.

RMT Real Money Trade. The practice of buying or selling in-game currency, items, or accounts for real-world money. Most games strictly prohibit RMT.

Roll The act of typing /random 100 to generate a number between 1 and 100. Rolling is the most widely accepted method of determining who receives a contested loot drop.

Root An ability that immobilizes a target in place without otherwise disabling them. Rooted enemies can still attack and cast spells but cannot move. The name comes from early implementations tied to earth and nature magic.

RP Roleplay. The practice of playing the game in character — speaking, acting, and making decisions as your character would rather than as yourself. Many MMOs host dedicated RP servers with communities built entirely around collaborative storytelling. Even on non-RP servers, pockets of roleplay communities can often be found in major cities or hubs.

RvR Realm versus Realm. Large-scale factional PvP, where entire server populations are divided into competing factions that battle for territory and dominance.

S

Server A single instance of the game world, capable of hosting a limited number of players. Most MMOs run dozens or hundreds of servers simultaneously, with players typically unable to interact across different servers unless they transfer.

Shard A synonym for server, originally used in Ultima Online, based on the lore that the game world was a shard of a shattered gem.

Solo Playing entirely alone, without a group. Some content is designed for solo play; other content is nearly impossible without teammates.

Soulbound An item that is permanently tied to a single character and cannot be traded, sold, or given away. See also BoE and BoP.

Spawn The moment an enemy or object appears in the game world, usually on a set timer. Used as both a verb (“it just spawned”) and a noun (“waiting on the boss spawn”).

Spec Short for specialization. Refers to a character’s chosen build — the arrangement of skills, talents, and abilities that defines their playstyle.

Spirit An attribute in games like World of Warcraft that governs how quickly a character passively regenerates mana between actions.

Stun A crowd control effect that completely immobilizes a target for a short duration, preventing all movement and actions.

SWG Abbreviation for Star Wars Galaxies, a now-defunct MMO set in the Star Wars universe. It was shut down following the release of Star Wars: The Old Republic.

T

TAB Team Arena Brawler. Describes games like Battlerite that blend MOBA-style combat with arena-focused team play.

Tank As a noun, a tank is a durable character built to absorb punishment and protect the rest of the group. As a verb, tanking refers to the act of maintaining enemy aggro so that squishier allies can operate safely.

Toxic Describing behavior that is hostile, abusive, or deliberately disruptive toward other players — trash talk that crosses a line, harassment, deliberate sabotage of group content, or sustained unsportsmanlike conduct. Toxicity is a persistent challenge in online gaming communities and a frequent subject of discussion around game design and player moderation.

Train / Training Two meanings: (1) A chain of mobs all chasing a single player, often accidentally dragged through populated areas — a nightmare for bystanders. (2) The practice of fighting monsters repeatedly to build experience and skill.

Transmog / Glamour Cosmetic systems that allow players to change the visual appearance of their gear without affecting its stats. Transmog lets you look exactly how you want, regardless of what you’re actually equipped. In games like Final Fantasy XIV, where it’s called the Glamour system, fashion endgame — the pursuit of the perfect outfit — is sometimes joked to be the true endgame.

Twink As a verb, to twink is to outfit a low-level character with high-quality gear they couldn’t normally obtain, usually gifted by a higher-level player. As a noun, a twinked character is one that benefits from this treatment.

Twisting A technique, most famously used in Dark Age of Camelot, where a bard rapidly cycles through songs so that multiple buff effects overlap simultaneously due to lingering durations.

U

Uber Borrowed from the German word for “super” or “above.” Used to describe something exceptionally powerful or impressive. “That sword is uber” remains a timeless compliment.

UO Abbreviation for Ultima Online, one of the earliest graphical MMORPGs, released in 1997 and still operational today in various forms.

V

Vanguard Vanguard: Saga of Heroes, a fantasy MMORPG by Sony Online Entertainment that launched with ambitious promises but failed to live up to them, fading into obscurity not long after release.

W

WB “Welcome back.” Said to a player who returns after being AFK or logging in after an absence.

Whale A player who spends heavily on microtransactions — far beyond what the average player pays. Whales are a significant revenue driver for free-to-play games, and much of the monetization design in F2P MMOs is built specifically to cater to and encourage whale spending. The term is borrowed from casino industry terminology.

Wipe When every member of a party or raid dies simultaneously, forcing the group to regroup and start the encounter over. A particularly brutal wipe can undo significant progress.

WOOT An expression of triumph or excitement. Synonymous with “hooray” or “yes!”

WoW Abbreviation for World of Warcraft, the genre-defining MMORPG by Blizzard Entertainment that still sets the standard for much of the genre’s vocabulary.

WTB “Want to buy.”

WTG “Way to go.” Technically encouragement, but used just as often sarcastically. “WTG pulling the entire dungeon, nub.”

WTS “Want to sell.”

X

XP Experience points. The currency of character growth, earned through killing enemies, completing quests, and achieving milestones. Accumulate enough and you level up.

xD A text-based emoji representing a wide open-mouthed laugh, often accompanying a joke or lighthearted comment.

Y

Yggdrasil The cosmic tree of life drawn from Norse mythology, referenced in many RPGs. Ragnarok Online in particular weaves Yggdrasil and other Norse mythological elements throughout its world and lore.

Z

Zerg A combat strategy that forgoes finesse in favor of overwhelming numbers — rush the enemy and bury them in bodies. Popularized by the Zerg race in StarCraft, which was built around exactly this philosophy. In MMO circles, zerging is generally seen as a low-skill, if sometimes effective, approach.

Zombie The undead staple of fantasy gaming. Zombies appear in virtually every MMORPG as early-game fodder — slow, weak, and useful mainly for introducing new players to basic combat.

Zone A discrete, separately loaded section of the game world. Different zones may represent different geographical regions, dungeons, or cities, and transitioning between them typically triggers a loading screen.
