An act of pleasuring ones bum on a warm radiator while ingesting food stuffs of extraordinary proportions. This is often done during a break in work or at the stroke of midnight. Observers can often seem bemused and have to be treated for mild shock as the belly of the beast enacting this routine sends one in to a state of despair.
