Fat Back

A person with a giant back, but an incredibly small penis. To make up for insecurities resulting from a case of babydick, a fat back will overcompensate and take advantage of any oppurtunity to brag about his or her hugeness, back or otherwise.

When everyone started talking about their penises, Mike the Fat Back quickly changed the conversation: "I'm the only one who can get this tattoo 'cause my back's so big"

1969 Mustang Fastback

Car driven by old men that think they are still cool. More then likely also have beat up Harley of some sort. The car will usually smell like bacon or jalapenos. The reason for this is still unknown.

"Hey look at that moron over there." "Wow! He must drive a 1969 Mustang Fastback."

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.
