The undeniably eerie feeling that you've seen all this shit before. ;->

Our new account manager just introduced himself and I had that distinct feeling of deja poo.

Fuck man.
What dumbass?
That damn school bus takes so long to get home. And I had to shit since the start of weightlifting - that shit makes you have to shit more when you do them squats, but anyhow I had to hold in that shit so long I started getting deja poo. It went out nice n easy, and damn it felt good.

Yo i gotta go take a dump
-5 minutes later-
Oh shit its a deja poo!

"Whoa, I've seen that corn before! That's a deja poo!"

Jane: Weren't you just in that bathroom??
Dick: I've got a case of DEJA POO!

Dude, what's wrong?
Yo, that burrito done laid me to the bone.

Man, it made you sick last time, you spent all night in the bathroom.

Damn, I gotta stop eatin that junk. I got deja poo.
