proof fuck

1. Most often used to mean sexual exploit with an ex to PROVE (once and for all mind you) that you either still have it...or have gotten better at it.

2. Sex with anyone just to prove you "can".

He looks pretty good these days...I might have to proof fuck his ass tonight!

I bet I can fuck that...I'll prove it.
