(Bee Em) An abbreviated form of BMW, "BM" is urban vernacular for a BMW automobile. Ask someone from the hood - they'll tell you. Since 1990 or earlier, all the way up to the present, the term "BM" has been frequently used in rap music lyrics - some you've heard - to refer to a BMW. This is not the first post to proffer this definition of "BM" but those posts are buried under stupid definitions. Voters, do you know what "Urban" means? Have you looked up the word, Urban on, say, Urban Dictionary? But didn't you come here because you already know the definition of urban but you don't know what nine piece means? I can at least understand how "bad manners" is the top definition - cuz korean invasion.. you guys have won this won - hangug-ui widaehan seuseungnim, jinsim-eulo seunglileul chughahabnida! But bowel movement? I'm pretty no one on any corner has ever uttered the words, "bowel movement". on ANY corner. ANY-WHERE. EV-ERRRR. "Yo son, hold this heater, son. Gotta have a BM baaad, son. Real rap, son!" wait, no: "real crap, son!" "Woa-day! - Come jose with me in the stall while I'm havin' this BM. You got a square?" "man, send it to the river!" In the United States, use of the term "BM" (bee em) to refer to a BMW is generally limited to urban settings. Outside the hood, and certainly on Urban Dictionary, pretty much no one equates "BM" with BMW. Pretty much everywhere else in the world, BM is the most common way to refer to a BMW.
