When a dude purposefully or accidentally stabs you with an erect penis through his pants. This usually occurs in crowded areas where people have to brush up against one another. Or inadvertently when giving someone a gives a prolonged bear hug or when spooning.
I can't bend over to tie my shoes in this crowded bar because I ll get will cockdaggered whether I like it or not from behind.
I can never spoon with my girl anymore when we sleep together because she wakes up cockdaggered in the middle of the night.
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.
