In the fast-paced world of League of Legends, every second counts. With team fights, strategic plays, and lightning-fast decisions defining each match, players have developed a rich vocabulary of chat abbreviations to communicate efficiently.
Among the most common and universally understood of these is the simple, two-letter abbreviation: “mb.”
So, what exactly does it stand for?
In the vast majority of cases, “mb” is shorthand for “my bad.”

This phrase is a quick and effective way for a player to apologize for a mistake, misplay, or miscommunication that impacts the team. Whether it’s a failed skill shot, a late rotation, or getting caught out of position, typing “mb” serves as a brief admission of error. It helps maintain the flow of conversation and keeps the game moving without requiring a lengthy explanation.
For example, a player might type:
- “mb, didn’t see the gank,” after getting ambushed by an enemy.
- “mb, I thought you were done,” when they accidentally take a teammate’s jungle buff.
- “mb, misclicked,” after a crucial skill shot misses its target in a teamfight.
While “my bad” is the primary definition in the League of Legends community, it is worth noting that in other online contexts, “mb” can carry different meanings. These can include “maybe,” “message back,” or “mind blown.” However, within the specific culture of LoL, its meaning is almost always an apology.
The use of “mb” is a simple but essential part of the game’s chat etiquette. It reflects the community’s culture of concise communication and sportsmanship, allowing players to quickly acknowledge their part in an error, move on, and focus on the next play.
It’s a key piece of the game’s slang that helps diffuse tension and maintain a positive gaming environment.
