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!

Flakbakar

An early Swiss plane tested in Brazil in 1909. It involves shoving a metal rod up the pilots ass. The test didn't end well and ended in severe prostate damage to the pilot.

I feel bad for the pilot who flew the Flakbakar.
