Backwash

When a guy or girl cums in your mouth and you hold it in your mouth only to deposit the goods into their mouth

Man that chic looked like a geyser when I give her a backwash. Dude that's awesome. Next time I see her I'll call her old faithful.

brazilian backwash

A sexual act in which the female stands over the male, who holds his anus agape while the female fingers herself until she squirts into his anus.

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.
