(noun) A deviant sex act in which you fuck a virgin in the ass so she can keep her cherry intact (a considerate move on your part) but when you're done, you punch her unconscious and smear grape jelly on her ass. Why? Why not. That, my friends, is a cherry pie vendetta.
When I first starting fucking her I wasn't thinking about it, but right before I blew, I knew I was going to giver her a cherry pie vendetta.
