Definitions
BM has two main lives in modern slang. In gaming, it means "bad manners" — taunting opponents, tea-bagging corpses, trash-talking in chat, or doing anything just to rub your win in someone's face. A classic BM move is spamming emotes after destroying someone. Outside gaming, BM is a polite euphemism for a bowel movement, used when you want to keep things clinical without being crude. Context is everything — "nice BM dude" hits very differently depending on the lobby.

It can be used without specific reference to the genders or orientations of those involved.
