BM

A multiplayer gaming term that refers to unsportsmanlike conduct during or after gameplay, such as typing something offensive to the other player, refusing to shake hands, or perhaps ragequitting.

An acronym that refers to the movement of food through a person's digestive tract.

The BM is the last step in the stool movement process as it leaves the body. Irregular BMs include diarrhea, constipation, and bowel incontinence.

BM stands for "bite me." Angry people of all sorts might tell you to bite them (meaning to back off or leave them alone) via online chat or text message.

"Bite me" has a long and storied history and, according to a variety of sources, may have arisen from one of several different more-vulgar sayings. Specifically and most interestingly, linguists cannot agree what part of the body the "me" in "bite me" originally referred to. These days, however, "bite me" is typically considered short for "bite me in the a**," an invitation that you're likely to decline.
