A Boppin' Bitch. Used as both an insult and in some cases as a term of endearment, a "boppin' bitch" will most likely be high maintenance and/or have a drug or alcohol problem. Regardless of this, your typical BB is considered more "boppin"(scatter-brained, opinionated, probably pretty, generally smart though at times making nonsensical decisions, etc.) than that of a bitch and many BB"s are actually very nice and generous people.

Boy: "Shut yo BB lookin' ass up, hoe"

BB means (in the most common use) baby, or babe. BB however is mainly an inside joke between my friends and I. However, I am doing the abbreviated version of bb and babe, so by no means does this not violate any rules.
