A thick, soup like excrement mixture, that sprays forth from the anus without warning, and may result in mud butt if not taken care of immediately.

That shit you take that feels like you're peeing from your ass, and looks like someone poured a can of chunky's soup in your toilet. Poop-Soup comes in 5 different levels.
Poop-Soup levels:

Lvl 1 - brought upon by a sudden discomfort, your stomach is in for a challenge.

Lvl 2 - the discomfort evolves into a pain, letting you know that your ass in a bit of trouble.

Lvl 3 - the pain is accompanied by an almost constant rumble, letting you know that only parts will come out solid.
Lvl 4 - the pain & grumbling are no match for the newly joined back pain, crippling you before you deliver your sloppy mess, which could be easily mistaken for a few Hershey kisses dumped into some chocolate milk.
Lvl 5 - the pain, grumbling,back pain, are all no match for the intense shivers & heavy sweats, this is a definite warning that your asshole will not survive. Nothing will be solid & the memory will haunt you forever, for this the highest level of poop-soup.
Person A: man my stomach has been really hurting, and i get these back pains at random.
Person B: uh oh, sounds like you got a bad case of Poop-Soup.

A combination of dog and cat loaves picked up in the yard and cooked over a campfire. The bowl weevils and roundworms really make this a tasty treat.
