Originally uttered by former DC mayor and current DC councilmember Marion Barry when caught by the FBI in a hotel room with crack and a prostitute in 1990. (He was still elected.) Now a catchphrase used occasionally by DC locals to express discontent with a situation, or to remind people that we had the original crack mayor - 20+ years before Toronto.
A female that lures a simple, and naive dudes into an unseen or bad situation (robbery or fight, or murder.)
Man! that`s a shame what happened to bruh. (scoffs) Dude should have known she was a Set `em up chick. Any female trying that hard, to get you to come a part town or area you don`t about is up something.
