Cab Drivers Ass 

When one performs or lets loose what he/she thinks to be a fart, and turns out to be a little wet turd that is squishy and warm between the cheeks. If left unattended, this mush may become rather irritable, uncomfortable, and smelly. This always results in a mess and sometimes may soil one's undergarments. One may relate this occurrence to a real life cab drivers ass.

Cab Driver's Ass 

Noun. Pathology.

1. The condition of painful burning in between the butt cheeks caused by the mixture of fecal matter accidentally expelled during a previous farting fit and sweat pooling up between them over an extended period of time. Symptoms of localized pain elsewhere, such as the parts with the most weight or folding are also common. Almost exclusively happens while sitting in an uncomfortably hot environment.

2. An extreme advancement of Swamp Ass. Most fatal cases are preceded by an untreated shart.

Idiom.

A case of cab driver's ass; inevitable: If you don't stuff some paper between those cheeks, you're gonna get a case of cab driver's ass.

"It was a long trip.. I finally got the kids to Disney Land, but the air conditioner quit working ten minutes into the drive and when I got there I had a flaming case of the cab driver's ass. I was so miserable, I flipped Mickey Mouse off and told Donald Duck to put on some damn pants. Did you know the Epcot Center has a secret dungeon? Yeah, security took me there."
