The act of a fat person driving in such a way that it reflects their loud, fat, lazy, and undisciplined personality. It is most often done in cars and vans from the 80s or late-model trucks. Fat-drivers always look unhappy in their automobiles.
"I tried to take a left into the parking lot, but some fat bitch was fat-driving down the center blocking both lanes."

"I wanted to back out, but some 400-pound guy in a Festiva is stopped behind me eating a chalupa. I honked so he'd pull forward, but he just looked at me while he struggled to breathe."

1. A man hating, butch kind of she male who wears CIA sunglasses when driving, has shaved hair a nose ring and plays an acoustic guitar to reveal the sensitive side of her personality.

2. A she male who's ass is as big as her truck
1. She's most likely to say: 'get outta the way small dick, i'm a fat truck driving lesbian and i'm gonna sing the times are changin'

2. She's most likely to hear: 'get off the sidewalk. there's a fat truck driving lesbian whose ass crack will swallow us'
