When someone places their lips tightly around another persons stink trumpet and they fart in your mouth and you swallow that fart like It's grandma's apple pie. Then you belch it back up and blow it in someone's face.

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.
