Poseidon's Wrath

A step up from a Poseidon's Kiss, Poseidon's Wrath occurs when you diarrhea so forcefully into the toilet that you not only get a bit of water on your butthole, but your entire exposed bottom is covered with diarrhea water, including your buttcheeks and ballsack/taint area. A Poseidon's Wrath means more wiping, due to the entire bottom becoming covered in shitwater.

"Dude, I heard that splash from out here. Was that a Poseidon's Kiss?"
"Worse... A Poseidon's Wrath."
"Ugh, god, yeah, you do still kinda smell like shit..."
