Extreme diarrhea. Nearly pure fluid generally yellow or light brown that comes forth while attempting to shit but finding out you have this problem. Shit that actually is more like piss
Scott: "After we had that $4 all-you-can eat Chinese buffet last night, I woke up with massive stomach cramps. I went to the can and was pissing out of my ass."

Max: "yea, I had the same problem, I went to the can to take a leak, finished, fealt I had to shit, turned around, sat down and ended up pissing out of my ass!"

When you have such explosive diarrhea that is in a completely liquid form (without the lumps) and feels as if you are pissing out of your ass. There is such a strong steady stream that a passerby who hears you could easily mistaken you for taking an actual piss.
I don't know what was in that meal, but I'm sure you'll be pissing out of your ass (POOYA) for hours.

a phrase repeated again and again in the popular TV show South Park - where one of the character's tourette's tick is repeatedly screaming variations of "piss out my ass!"

also, when the character is screaming a variation of this phrase, he will turn his head to the side and cover his mouth.
