An innuendo used to describe the T H I C C posterior of the mother of your own mother/father. More specifically, when it is old and smells peculiar like an old cheese wheel.
"I was having a pretty shit weekend, luckily I got a bit of Grandma's cheese wheel which made things more bearable."
When a young adult has sex, usually in porno's, with a mature woman (60+) and licks her vagina that hasn't been shaved nor cleaned. This creates a foaming substance, almost like cheese, where the young man takes it and shoves it into her anus, where the cheese like substance is used as a lubricant.
"Yo dude, Jack played with that grandma's fuck cheese last night. Eck!!"
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.
