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 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!

flat cat

A cat in a hoader's home that has " been lost" or "run away". Essentially the cat has died due to lack of care or unlivable environment and has become compressed by the hoard. Related to a sail cat.

Is that a flat cat under those books?
