DnD Acronyms List: OMG – What are BBEG and TPK?

Last Updated on January 22, 2023

Jumping into Dungeons & Dragons for the first time can feel an awful lot like trying to learn a whole new language.

On top of learning a sprawling, complex ruleset, you’ve got a near-infinite universe of adventures, lore, and preconceived notions that have grown and developed across almost 50 years of different editions and innumerable hours of debate throughout the community. 

Then you’ve got all the strange assumptions about everything from behavior to appearance that forms an extra layer of understanding within the community: bards are horny (not necessarily), tieflings are purple (in the actual rules they’re not), goblins are murderous little psychopaths (less and less these days), and so on. 

It can be a little daunting – kind of like you’re stepping into a strange new world. 

And then there are acronyms. Woof. 

“Well, the RAW in the DMG say that AC is affected by the DW feat, so the BBEG’s AoE feature does reduce that by 2, meaning that his AoO hits. Ouch. Looks like it’s gonna be a TPK.”

Like I said, woof. 

While this guide isn’t going to explain how grappling works, or the difference between demons and devils, or why something having two arms, two legs, and a head doesn’t actually mean it’s a humanoid, it will hopefully make the endless sea of acronyms that exist throughout D&D (more acronyms before we’ve even begun!) a little less daunting. 

To make things a little easier to parse, we’ve broken them up into different sections. You can navigate to any of these sections using the drop-down below.

It’s worth noting that, while some entries like AC and DM are going to come up all the time, there are a bunch in here that are going to be somewhat rare. We’re not promoting the adoption of new and unnecessary initializations, but rather trying to put together the most comprehensive list possible.

We’ve also included a few common acronyms that don’t technically belong to D&D but are often found in the game’s orbit. 

Also, yes I’m aware that an acronym is technically only an acronym when it spells out a new word (like Greatest of All Time’s acronym is GOAT); otherwise, it’s an initialism.

I know it’s wrong but that’s the way the SEO wind is blowing, so don’t tweet at me.

General Terms 

D&D/DnD: Dungeons and Dragons. Obviously. 

DM: Dungeon Master. Also known in other roleplaying games as the GM (game master, gamesmaster), guide, and keeper of secrets, the DM is the player who runs the game, creating a story, portraying the people, places, and things within it, and arbitrating the rules of the game for the players. 

PC: Player Character. The person you as a player inhabit at the table. 

NPC: Non-Player Character. A person portrayed by the DM. 

DMPC: Dungeon Master Player Character. A (somewhat maligned) term for the Dungeon Master’s self-insert character. 

BBEG: Big Bad Evil Guy/Girl. The term is used to describe the main villain of an adventure or story that is behind the main threat the party faces. The term is used to distinguish between other powerful enemies like bosses and minibosses. One of the more famous BBEGs is Count Strahd von Zarovich from the Curse of Strahd adventure.    

RP: Role Playing. Acting out what your character does and says. 

IC: In Character. Saying something as your character or acting on information that your character knows. 

OoC: Speaking as yourself; discussing things that your character might not know. 

PvP: Player versus Player. When one player character acts against another. Some DMs don’t allow PvP at their tables, as it can involve one or more players feeling as though their agency is being constrained.  

PvE: Player versus Environment. When a player character fights monsters, NPCs, or otherwise interacts with the world of the game that doesn’t involve their fellow PCs. 

RAW: Rules as Written in the official source material. Usually used in debates over how certain interpretations of the rules – as well as how some rules interact with others – can be used to produce especially strange or “broken” effects. 

RAI: Rules as Intended. Some RAW can be exploited through careful interpretation. RAI tries to interpret the intent behind the rules, rather than treating them as a contract to be wriggled out of.
