The feeling that the same shit keeps happening over and over to you.
I think I'm having Deja Poop. Didn't you try and pull this same shit last week?
I'm having Deja poop, this shit always happens when I date strippers.
The feeling you have taken a shit like this before.
Sitting on the toilet, too many wings the night before, an eerie dread of deja poop occured.
