short for electronic penis, this is used for losers on the internet to try and boost their self esteem by using a facticious item such as the epeen, usually refered to in size.
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 feeling that the poo you just experienced may have resulted in a tearing of the perineum, not unlike the tearing a woman may experience during childbirth.
Person One: Why are you sitting on a pillow, today?
Person Two: Tamales with chili for dinner last night...resulted in an epoosiotomy of gigantic proportions. I'm still not sure I don't need stitches.
The act of having a sudden intuitive leap of understanding all while dropping a deuce.
Joe: Dude what took you so long?
Nate: I'm really sorry man, but I was taking this massive dump and it just came to me.
Joe: Wait what do you mean man?
Nate: I'm....I'm... Muslim
Joe: Wow man! You shit so hard you had an Epoophany!
Nate: Wow dude! Praise be Allah
