When a big smelly fat guy is so abnormally huge, he cannot normally bathe due to the inability to fit in the bath.

Therefore mister fat ass has to remove the shower head. From here fat ass will proceed to sit his giant hole on the edge of the bath while running the hot water from the hose pipe directly into his brown eye.

This act of cleaning by the fat ass, generates a byproduct known as ass water.
Person 1: Hey man, did you see Pip is so fat he washes his hole into the bath with the shower hose.

Person 2 : Yeah I heard about the fat bastard, imagine getting a mouthful of that ass water....yock!
