Fex

When a guy and a girl are having sex, and the guy likes to look at her pictures online, to keep him "in the mood" and remind him that she's WAY hotter online than in real life.

So how was Laura Diggelhoop last night?
Dude, I had to have fex with her!

Fex

A fight that happens while having sex.

Jeremy and I were totally going at it when I mentioned something I had no idea would start a fex; I didn't realize how mad he was until he lost his boner.
