Flat Earther

Someone who doesn't believe something if they see it right in front of them.

We sent a flat Earther into orbit, and he said he thinks the windows distorted the Earth to make it look round, so he wouldn't be able to trust his own vision.

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-waps

1. Breasts of a usually older and over-weight female which are saggy, long, flat and astoundingly repulsive.

2. Breasts that when not upholstered by a bra hang so low that they pose a serious trip hazard to the lady who they belong to.

"Is she a milf?" "No fucking way, she's got flat-waps and bingo wings!"
