The phenomenon of sitting down to have a poo and, whilst pooing having a brilliant idea also. A little bit like the Eureka moment famously experienced by Archimedes.
Archimedes: ...and so it just came to me in an epoophany, of course the toilet water rises cus its now full of poo! Eureka!

Archimedes' Chum: You should change it so it was just you in the bath, no one really likes poo.

The sudden and imparitive urge to take a massive shit.
Jenny: "MOTHER FUCKING DAMN SHIT! I'm in the midst of an epoophany."
Jack: "Hurry! Find a bathroom before your intestines explode!"
Jenny: "Can't. Go. Any. Further." *Shits in the street*

Get the Epoophany mug.
A sudden "brilliant" realization that, upon reflection, turns out to be stupid (often immediately after you've shouted it out to everyone within earshot, or, worse, published it in a public forum).
"John had a really embarrassing epoophany in math class yesterday; he thought he'd figured out that all odd numbers were prime (because 3, 5, and 7 are) and tried to prove it in front of the whole class."

Get the Epoophany mug.
The act of having a sudden intuitive leap of understanding all while dropping a deuce.
