Backsplash bidet

When the contact of faeces with toilet water results in a splash of water directly hitting theanus while defecating.

Pablo: Man, I hate it when my ass gets hit with backsplash; especially when I’m squatting over a public toilet, avoiding ass cheek contact with the seat, like an MJ dance move.
Mateo: It’s not so bad if it’s the backsplash bidet and the water hits you right in the asshole.
Tomas: Yeah, that makes for a quick and easy wipe.

colonoscopy backsplash

When you're giving a colonoscopy, and the patient voluntarily or involuntarily releases gas and/or fluid, resulting in a "backsplash."

Guy 1: How was work? Knock out a lot of colonoscopies today? You are a colonoscopist right?
Guy 2: That's not a thing, but yeah, unfortunately it wasn't great though.
Guy 1: Why??
Guy 2: Well, one of my patients ate way too much Carl's Jr. and I had to deal with mad colonoscopy backsplash. I don't think my shirt will ever be the same.

Blue Water Backsplash

When you take a dump in a port-a-potty and that nasty blue water that everyone else's grody is in comes back up and splashes you in the ass.

I always throw a wad of toilet paper down before I lay a log in the honey bucket to avoid the Blue Water Backsplash.

Chinese Backsplash

A water stream shooting into one's rectum after a turd has plunged into the toilet. May sting.

'"Dude think I got aids from the chinese backsplash in that truckstop bathroom."
