Similarly to hoop stress, poop stress is the result of an internal pressure acting on a thin walled pressure vessel. The internal pressure is usually due to grade F fast-food diarrhea or the buildup of dairy queen fart gas.
It should also be noted that the temperature in the vessel is directly proportional to the pressure incurred. see hot shit
Damn, i have the gnarliest poop stress from those jack-in-the box tacos I ate last night.
When you take a five doller bill and wipe your ass with it and throw it on the ground. A stranger comes by and picks it up with said shit on the bill and you yell Poop Doller.
(Great for Balcony fun!!!)
Jim was so desperate for crack he didn't care about the assholes yelling poop doller when he found five dollars.
