Fat lip or Fat lipping happens when a couple is interupted while making out, either by a room mate, a parent, etc, and one person gets hit in the mouth with an elbow.
Dude, I was totally making out with her, and then my Bro walked in and she totally gave me a Fat Lip
She totally Fat Lipped me.
She totally Fat Lipped me.
