Non-Yeathead: Yo, you heard of this rapper named Yeat?

Non-Yeathead: How do I ascend like you?
Yeathead: Become a yeathead
This is a sexual act that often occurs from a guy setting off the girls gag reflex while she is giving him head, thus causing her to puke all over his junk.

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.
