look up any word, like bukkake:
A waterfoul happens when you are in the shower with your back turned towards the shower head. While letting the water run down your crack, let a big fart loose, the water muffels the gas making it sound like you are taking a shower with a duck or goose. QUACK, QUACK!!
Be sure it is just gas. A waterfoul is hard to clean up.
