The extreme attempt to carry one something that is already resolved or no one cares about. The extreme case up the idiom, "beating a dead horse".
The cocky douche bag was beating a dead horse by rubbing his victory on the loser. However, he preceeded to raping a dead horse by talking trash to the loser for the next 20 years.
If everybody thought the same, then they would all bet on the same horse, then nobody would make any money. Hence, different views make horse racing possible.

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.
