One person is designated as 'The rain catcher' several others position themselves on the roof of a house, they then begin to urinate from the roof as the rain catcher attmepts to catch all the urine in his mouth.

When they are finished, if it is deemed the rain catcher has not caught enough rain a high pressure hose will fire watery liquid shit over his or her face and into his or her mouth
