AM BM 

Morning (AM) bowel movement (BM). The first poop of the day, almost always taken immediately upon awakening in the morning.

A "beer dump" is a type of AM BM, but not all AM BMs are beer dumps.

"I can't even start my day with some coffee until I've had my AM BM."

"I didn't have time for my AM BM this morning so I've had to hold that sh*t in all f*cking morning."

ambm 

Ambm is shorthand for Albanian model biker man. People usually refer to very attractive Albanian men who look a little bit edgy as ambms. Ambms have vibes similar to "Cry Baby" Wade Walker. Sometimes people who aren't Albanian are called ambms if they are particularly attractive enough, having sharp angled features and also the edgy vibe. Ambms usually look pretty tough on the outside but are actually kind of softies on the inside. Ambm is generally used in places NYC or Detroit where there are large Albanian communities.

-Oh my god did you see him yesterday? He's such an eboy
-He's not an eboy he's an ambm
