The Eye-of-Rhea

The period after taking a horrible shit (diarrhea) in which your body deceives you into believing you're finished shitting, only to have your diarrhea come back soon thereafter.

John: Dude, I just diarrhea'd everywhere and got that Taco Bell out of my system.

Mike: No dude, you're just in The Eye-of-Rhea.

John: What're you talking ab...oh man...
