Origin & Background of BM
The BM meaning grew from several worlds at once. Doctors have used BM for bowel movement for ages, since it’s a discreet shorthand. Dictionaries also list baby mama as US slang that can be derogatory.
The “bad manners” sense came from competitive online gaming. Gaming writers say it likely started in StarCraft, then spread to League of Legends, Dota 2 and Hearthstone. Players used it to call out taunting and trolling, and “BMing” became a verb for acting that way. Some players call it harmless trash talk, while others see it as toxic behavior, so opinions are split.

The emotion behind the BM meaning changes with each use. In gaming, it often signals frustration, ego or dominance. Players use it to call out rude behavior, but some use BMing to provoke others.
With “baby mama,” tone is everything. It can be a neutral label, but it can also sound dismissive, especially if said with sarcasm. For health or work meanings, the tone stays practical and calm.
