A flat slut is somebody named Amy who has been in a terrible sexual accident and had their face smashed against a woman's extremely flat breasts. This caused her face to become as flat as a piece of paper. If you ever meet a Flat Slut, don't get too close because she will reel you in and turn you into a condescending dick who gets really annoyed when their threesome with Amy doesn't go to plan because Geraldine doesn't know how to use a vaginal condom.
Guy 1: "Ugh, I met this flat slut at college today."
Guy 2: "Ew, was she flat?"
Guy 1: "Oh yeah, flat as a rat"

term used to describe a fake butt. i.e. chick used to have a FLAT ass but then went to get work done to FIX it.
Commonly used is the phrase "Fix-A-Flat, bathroom caulk & cement OR cornbread, grits & blessed?" Which is said to another male admiring the same donkey booty asking him if he thinks the ass is fake or real.
