Fate Fuck 

Realization, after the fact, that your one night stand was someone you already knew.

Shazam randomly meets Pepsi on a Friday night. They fuck. She stalks his facebook Monday morning only to discover herself in his old photos. Banana says "that`s fate." Shazam says "No, it`s a fate fuck."
