Used to describe someone that does not fit the cultural norm in the area.
Marcus: Yo son, check you out. What the hell you wearin?
DeRon: Man, I passed out at Shenna house last night. Had to raid her brotha’s threads.
Marcus: Aw hell naw. You a total bama.
“Bama” was originally coined to refer to people from Alabama, or anywhere else in the south, that had moved to the north. Their style was obviously different and stuck out among the locals. It has changed into a term used regularly in the Washington DC area to describe a person that stands out and looks out of place or awkward.
It is used in 50 Cent’s song “Poor Lil Rich”
