When you take a shit and the water from the toilet touches your penis
"Dude, last night after that Mexican food gave me a Poseidons Handjob"
When a bidet accidentally shoots up your butthole.
"Dude, your toilet just have me a Poseidon's Rimjob. Lower the water pressure."
When you take a shit and the water splashes so hard directly on your asshole that it becomes clean enough you don't have to wipe anymore.
Joe: Have you ever used a bidet?
Jeff: I didn't need it, i got the Poseidon's RimJob!
When you have to poop but you don't want poop on your hand so you put toilet paper around your hand.
I Had to poop but i didn't want to get poop on my hand so i used poseidon's glove.
When you drop a sizable dump into the toilet creating a splash back with sufficient height to be able to reach the anus. The Poseidon’s Tongue is the one drop of splashback that licks inside the anus
Dave: wow, I dropped a hefer of a dump and ended up with a Poseidon’s Tongue
Keith: that’s horrendous, you poor bastard
The defender of bubbles. The act of taking a dump in a bubble bath and playing with it
‘ here he comes. Chocolate Poseidon the defender of bubbles’ Said Nick whilst holding his dump in the bath.
A close relative of Poseidon’s Kiss, this is the exhilarating feeling of refreshingly cool, semi-moist air circulating your anushole after flushing the toilet while still sitting upon it.
I was having a fucked-up day until I went to sit down for a grumpy shit and was blessed with Poseidon’s Breeze tantalizing my butthole.
