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 Brimmer

Someone that's into "extreme" sports such as down hill mtn. biking, BMX, motocross or anything that you can get "rad" with. A flat brimmer will wear a ball cap with a flat brim with Oakley sunglasses and can usually be seen drinking a Monster Energy drink. A flat brimmer will think he or she is better than the rest and loves to pose for photographs.

Did you see that flat brimmer with the Fox jersey acting like a douche to those other riders?

Fix a Flat

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.

Tyrone: Yo check out that phat ass over there..."Fix A Flat, bathroom caulk & cement OR cornbread, grits & blessed?"
Shawn: look at that shit, shit it definitely fake
