The male genetic disposition for having a flat ass. An ass that has no POW! or lacks badunka dunk. Most commonly associated with male Caucasians, white-guy butt (or WGB) can also be found on other male members of all races.
White-guy butt is not to be confused with computer ass, which results from a lack of activity associated with hours and hours of daily computer usage.
Dude: Stupid white-guy butt, my pants keep falling down 'cause I got no ass!!!
Some douchebag: are you and that other guy gay?
Me: No, we're just guys who stick their penises in other guy's butt holes, huge difference
Some douchebag: I see no difference
Me: It's cuz we say NO HOMO so that makes it straight. Then we go back to fucking girls right in the pussy
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.
