Word for the girl you sleep with and refuse to call her, unless its for more sex. Also a way for friends to notify other friends when the booty call is in the vicinity.
Guy 1: Dude did you see M.F.?
Guy 2: Yeah! She walked by your job, and was looking for you.

Guy 1: Ok, shout out M.F. if she returns.
