A Muffler with an excessively and impractically large diameter output pipe (or an excessively large tailpipe on cars with mufflers located further from the rear of the car) - especially one that is mated to a much smaller upstream exaust system. Typically used to make a car "look fast" as opposed to modifications that actually make a car faster.
This type of exaust is called a "mellon shooter" because it is large enough to launch a melon that would be inserted into it - if the engine had enough power.
Look at the melonshooter on that Civic - it's as big as a sewer pipe!
n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the internet because it cannot be obtained elsewhere. Not legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the gamealive", so to speak.
Doom II is not abandonware because idstill sells it, while The Incredible Machine is not sold, therefore is abandonware.
Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
Butthead: Shut up, Beavis! (uh huh huh huh)
Beavis: Um, okay. (heh heh heh heh).
