Pronounced "Shy-tiss"

It's a combination of having the shits and the itis. You go out, eat big meal from a questionable buffet and spend the rest of the day either crapping your pants or falling asleep, or worse, both simultaneously.
Gary: Hey Pete, you ain't looking good.

Pete: Ug, I ate at Number 1 Super Indian Buffet for lunch. Now I got the Shitis.

Gary: The what?

Pete: the Shitis. I keep falling asleep whenever I'm not pooping my brains out.

Gary: Shitty.
