A very runny poo. Usually caused after one eats many prunes or similar foods. A bum pee is liquidy but may contain other chunks of food (peanuts, corn etc)
"I hate bum pee" (Done best in a British accent)

Tap Ass Pee Bum is usually obtained on a trip to Mexico after drinking the water.
The emitted sound from Pee Bum sounds like someone urinating when in actuality,it is stinky,liquid shit exiting with the force of a pressure washer.
Pee Bum will only stop or slow with medication or corn blockage.
