The act of someone walking in on you masturbating when you're cumming so you have to do the Cum Cutter and stop.
I was stroking it last night and my sister walked in so I had to pull the good ol' Cum Cutter. Needless to say, I can never look at my sister the same again.
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.
