look up any word, like bangarang:
F&P stands for Fuck and Punch. At the the conclusion of a one night stand, the girl punches the guy in the face as hard as she can, then proceeds to leave without ever explaining. Note: The chick will never have recollection of the event.
Julia: "How'd it go last night?"

Stef: "It went awesome. Not only was he large and in charge, I also F&P-ed the bastard too."
