Just pronounced "bad" in a social situation. An acronym for "Bitches Acting Dumb". Used to refer to any females feeling the need to act like an idiot to draw attention to themselves.
Person 1: "Hey, you see that chick acting like she's hammered when she only had like a beer and a half?"
Person 2: "B.A.D, man."
Person 2: "B.A.D, man."
