Full phrase: "What crawled up your ass and died?" It is said after somebody farts and the smell is so horrible that everyone in the room runs out gagging. The implication is that the fart smells as bad as, for example, a rotting dead skunk or maggoty rat.

In 1966, Andy Dufresne escaped from Shawshank prison. All they found of him was a muddy set of prison clothes, a bar of soap, and an old rock hammer, damn near worn down to the nub. I used to think it would take six-hundred years to tunnel under the wall with it. Old Andy did it in less than twenty. Oh, Andy loved Geology, I guess it appealed to his meticulous nature. An ice age here, million years of mountain building there. Geology is the study of pressure and time. That's all it takes really, pressure, and time. That, and a big god-damned poster. Like I said, in prison a man will do anything to keep his mind occupied. It turns out Andy's favourite hobby was totin' his wall through the exercise yard, a handful at a time. I guess after Tommy was killed, he decided he had been here just about long enough. Andy did like he was told, buffed those shoes to a high mirror shine. The guard simply didn't notice, neither did I... I mean, seriously, how often do you really look at a mans shoes? Andy crawled to freedom through five-hundred yards of shit smelling foulness I can't even imagine, or maybe I just don't want too. Five-Hundred yards... that's the length of five football fields, just shy of half a mile.

Term used to describe an unusually bad smelling fart. The implecation is that the fart smells like a rotting animal combined with shit.

A creature so horrible that if you look at it for to long, your eyes will start to bleed. Lives in drainpipes and grease pits surrounding high schools and universities. The origins of the abomination goes something like this: a giant plague infested sewer rat rapes an AIDS carrying orangutan, in the ass, while in the restroom of a 747. The orangutan proceeds to shit out the ass baby that was conceived. The baby abomination gets ejected out of the plane along with a large amount of shit. While falling, the abomination gets hit by lightning and catches fire. Upon reaching the ground, the flaming abomination slams into a mountain side at terminal velocity and then rolls down the side, hitting every rock on the way down. Baby Bom-Bom then reaches a cliff where it falls off, still on fire, and lands on the ugly tree, where it falls hitting every branch on the way down. It then falls into a campground, still on fire, where a family proceeds to beat it with sticks and stomp it out with their golf cleats. They then dump it into an outhouse that has a good 20 ft of shit in the bottom. Here the abomination matures, stewing in the shit of countless years.
Finally, the Abomination crawled out and made its home in the sewer system of a small north Georgia town.
The power of its ugliness attract other uglies like a magnet, so there is an excess amount of nasty in this town.
Seriously, this thing is so ugly that you will want to die when you see it. Its smell is indescribable, but ...

The act of crawling on your stomach after doing something illegal.

A term to describe someone who just got out of bed and used minimal hygiene before presenting himself/herself to the world. Usually done by people who partied like a rock star the night before. Something worse than bedhead.
