Invented at my school(I wasn't a part of this), The Poop Stack is when people continuously defecate in one toilet over and over again until the point where it is almost falling off the toilet. It is a mountain of towering shit that almost caused the school to shut down.
"Hey have you contributed to The Poop Stack?

Not yet, I'm having Taco Bell tonight, so I'm going to do it after".
