Unzip

On the toilet and the pressure builds, instead of a solid you get a pop and an explosion of diarrhea. Will occur most likely after a taco bell session or in someone who is lactose intolerant who chooses lactose over life.

"I sat down and instead of a clean and easy number 2, my body unzipped itself."
