Fatback

When you slap your stomach so hard your back jiggles

Dude you see that fatback hit the water.

Fatbacks

The three racers in Mario Kart 64; DK, Wario, and Bowser, that are scary to get around or hard to pass. If a smaller racer runs into the fantasses, they spin out. So called because of their wide backs.

Frickin’ Fatbacks, I just ran into DK on the bridge and fell in the lava.

Flatbacker

Some lady who thinks its ok to make her way on her life path while being flat on her back, giving up what's between her legs, in order to get there.

I can't believe how that chick sits back and gets paid, is given a car, and she is just a foul flatbacker!

Flatbackerackah

The flatbackerackah is a word used to describe the boney lump a minority of humans have at the back of the head. Researchers believe this is a trait derived from neanderthals.

Scott: Pedro, whats that weird lump on your head?
