Cleaving the buttocks in twain. Similar to a danza slap right along the buttcrack.

The bitch didn't like it in the ass so I had to teach her what's what with a Fatback Chopper.

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.
