When a bidet accidentally shoots up your butthole.
"Dude, your toilet just have me a Poseidon's Rimjob. Lower the water pressure."

Get the Poseidon's Rimjob mug.
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!
