When you shit in someone’s toilet and don’t flush while they are out of town and leave it to rot until the homeowner returns
Andy got mad at his uncle for yelling at him for stealing his credit card and using it on 1-800 phone sex numbers while his uncle was out of town, so Andy made a Grunny in the toilet before he left the house to show how ungrateful he was for the money he stole.
