BBM

Big Bowel Movement. When one has a larger than usual bowel movement.

Also Why Black Berry Messenger's abbreviation of BBM is poorly planned.

1.) I had a huge dinner last night and just had a BBM, someone should clear the toilet.

BBM

BROKEBACK. FUCKING. MOUNTAIN.

BBM stands for 'Brokeback Mountain,' a movie about two male cowboys who fall in love. Starring Heath Ledger and Jake Gyllenhaal. Directed by Ang Lee.

Also referred to as 'The Gay Cowboy Movie,' by those too ignorant to realize it's so much more than that.

No one will go see BBM with me. Fucking homophobes.

BBM

BlackBerry Messenger. A messenger just like Windows Live Messenger, but with a fancy name, although Windows Live Messenger offers much more features such as webcam, video calling etc... Yet BBM is a handy tool to get you killed on the road while driving, to the extent of distraction and addiction it offers.

Person 1: Hey, wheres Jimmy? Haven't seen him in a while..

Person 2: Yep, he's long gone. Got BBMed on his way to work..
