An exclamation you yell at a girl when you think she is purposely dressing much older than she really is. It's a warning signal to other guys who may be foolish enough to try to tap that ass. Also known as jail bait.
Jack and Rich are staring at this scantily clad girl across the way. She has a young face, but is dressed like a prostitute. Bernard comes to their rescue.

Bernard: Dude, what the fuck are you doing checking out that young'n? Shes Fo'TEEN!!
Jack & Rich: Oh shit!
Slutty girl: Hey, fuck all of you!
