the most horrible illness known to man; having explosive colon means you will shit so much at such a rapid speed that you won't even have time for a courtesy flush; known to leave toilets in ruins and causing entire sewage systems to fail; accompanied by severe anal pressure
One day I ate food at the school cafeteria. The next day I was in the bathroom and I had to shit sooo bad that I felt my colon burst into flames as feces blasted out of my burning ass and decimated the toilet and most of the floor.

What the AHS students have to look at on a random basis in the stall on the right in the upstairs Boys Bathroom; term used because the remains in the toilet looks like a colon was exploded with TNT and the rectum was pointed at the toilet.
The explosive colon has returned and it looks more disgusting then ever
