look up any word, like darude - sandstorm:
The intense and sudden release of bowel movements; creating an explosive (sometimes messy) bowl of poop. Soupy Poopie often comes unexpected, thus creating a sticky situation. Several causes of this common and unpleasant bodily function are; excessive drinking, bad Mexican food or "water", certain allergies and the extreme use of chewing gum. This catastrophic event on the body is like a fire drill for your "waste management team".
"Dude, DO NOT go in that bathroom I just unloaded a soupy poopie!"

"I drank so much last night, but after that huge soupy poopie there's not an ounce of alcohol left in me!"
