big ugly slut, that always lurks for attention of all the guys. Like a leech she will latch on to them and suck their.....(DICK). She is usually found getting shoved around by a bunch of guys but she will be laughing about it because she craves the attention and doesn't want to risk losing her crowd. Alot of the time she will run down the man shes leeching and keep yelling his name even though the guy doesn't notice her or care, she won't stop until he actually talks to her. B.U.S's also like to be treated like crap and a majority of them are B.D.O's too at least if there's some blacks around
Paul: Uhh Joe you got a nice B.U.S behind you right now...
Joe: REARY!?! WUR?
Paul: ROFL JK ITS UR MUM!!.
Joe: ACKUGH!
Paul: hey i'd totally push that man
Joe:......Well it is your birthday..hmmm..O.k.
Paul: THANKZ MAN!
Joe: Happy birthday Paul!
