When someone is passed out on the bathroom toilet everyone in the house jerks off on his face. After group ejaculation is complete a jar of olives is dumped on the victims face representing the olive branch in the noahs ark fable. To simulate the biblical flood the tub is plugged and ran on full as well as the tiolet made to overflow. When the victim realizes his demise he is laughed at and dubbed noah for the remainder of his life. If pets are present in the house they are all locked in the bathroom with the flood.
Willy passed out at the party last night and everyone there pulled the old "nasty noah's ark" on him. We all laughed and started calling him noah.
