When every molecule of shit in your body exits in about 1/1000 of a second, literally exploding out of your ass. The type of poo that leaves poo niblets in the toilet bowl long after you've left the bathroom.
I had to go so bad, the moment my ass touched the toilet seat I had a total explode-a-poo. I think some bounced up and stuck on my ass.
