revenge fuck 

To have sex with somebody (usually after a break up) because they look like your ex. This will usually help in getting over the break up by helping you move on to having sex with another person, while at the same time giving you a feeling of revenge towards your ex.

In the Entourage Pilot episode, Turtle is telling Eric that he has found some girls to come back to the house for the night - one of whom looks like Kristen, Eric's ex-girlfriend.

TURTLE
I’m on ass patrol. I’ve got a six pack, one of them kinda looks like Kristen.
ERIC
What are you, an asshole?
TURTLE
I’m just saying – revenge fuck!
ERIC
What, I’m gonna revenge fuck someone just cuz she looks like my ex?
TURTLE
Pfft, I would!
