The act of shitting in a condom. Freezing the package. Then peeling it and proceeding to fuck one's self.
Normally carried out by filthy hood rats, but often as a gay act of love!
That girl's fanny was minging man. Smelt like she'd been nut roasting herself!
Similar to a spit roast, only with more nuts involved. eg. a gay spit roast.
"Fancy coming back to mine for a nut roast?"
