Ballinasticfuckerdomeness is the highest level of awesomeness that can be achieved between two people. It is thought to be discovered by two drunk teenagers in July 2011, when they used the Awemometer to measure their awesomeness. The Awemometer shattered and the glass shards spelled out "Ballinasticfuckerdomeness".
Gosh, I can't even look at you two. Your ballinasticfuckerdomeness just makes me want to bang you both, at the same time.
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.
