Hiney Sludge is a common form of diarrhea that resembles the consistency of Mississippi Mud Pie. It often pours out of the asshole, slapping against the toilet water with the assistance of multiple fart blasts. This typically leads to “Poseidons Kiss”, or the splashing of water onto The Asshole. Though it is less severe than Hiney Piss, Hiney Sludge could be pretty chaotic and inconvenient and in fact cause Raw Asshole as well. Hiney Sludge is often referred to as “The Cousin Of Hiney Piss”.

When your ass is so saggy that it pushes up against your thighs and creates a second smaller ass between your first ass and thighs.

The most extreme form of diarrhea a human being can encounter. The signature key to knowing you are suffering from Hiney Piss is the fact that it literally sounds like you are pissing from your asshole. There is absolutely no solidity to this form of diarrhea, it is pure liquid. Hiney Piss is not a one time event either, usually a human being will suffer from Hiney Piss for an entire day, or even longer. A major side effect of Hiney Piss is a Raw Asshole. This is due to the constant wiping that is being done when suffering from Hiney Piss. It is recommended to use Wet Wipes when dealing with Hiney Piss.
Friend: "Dude are you okay? The bathroom smells like a rotting corpse!"
"I'm okay brah, I am just suffering from some really bad Hiney Piss"
