WTFITB=Who The Fuck Is That Bitch?!?!
The question one asks in a very
confused and/or disapproving manner when they surprisingly come to know about the
new chick in the group.
When you're hangin out with your usual circle of
friends and all of a sudden a new chick joins your
crew and starts talking to you
like she knows you and you look over to ur BFF, confused, and whisper 'ummm, who the fuck is that bitch?' Or 'WTFITB'
