1. A segway leading to a good thing or immediately proceeding a good thing.
2. An exclaimation expressing joy or satisfaction in a situation. Usually is based on the humiliation of another person, much like pwned. Correct use involves a long rant or insult with "bickitybam!" added to the end.

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.
