when all of your bodily functions happen at the exact same time you let out a loud yelp noise and your body has no choice but to die, anyone that witnesses a screaming shit will also have a screaming shit because it is highly contagious, and no cure exists
When you have the absolutely worst case of diarrhea that you feel like
Jeff Daniels did on the toilet in Dumb and Dumber and the pain is too
much to bear.
When you drink too many glasses of milk or some lowdown bastard spikes your food
with laxative or you eat too much spicy food, you'll know for sure you'll get them, and
you'll be on the can for a good long time having the screaming shits.
