It's also short for bridesmaid and breast milk, depending on the board. I think most people use it as a quick way to get their thoughts down without having to spell everything, just like DD, DS, DH, SW, etc. People on this board in particular know we're not talking about poop.
I would understand if it was a case like BF which could be Birth Family or Birth Father but BM I think everyone in this board knows that BM is for Birth Mom and not Bowel Movement...at least I would think.
