Flat Slut

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"

flat porn

Flat porn is visual pornography that is flat in nature, like a regular static image (think Tumbler or old school photos). It is not available in a 3D, interactive, or virtual (think Occulus) way.

My husband is not allowed to watch virtual porn, flat porn is fine because there is no depth or interaction with it!

Rainbow Flat

Something that is flat but isn't, usually a cycling route or event, yet not stupidly hilly.

Coined by Audax Club Bristol members after their president Paul Rainbow referred to the 1200km long distance cycling event Paris-Brest-Paris as flat to ease any pre-event jitters; it wasn't!

Is it a hilly ride?
No, it's Rainbow flat!

Flat-Earthing

When someone makes an arguement about something very stupid but no matter how hard someone proves them wrong, they make even dumber counter arguements over and over until the person gives up trying to prove them wrong.
