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.

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.

She's so special to me, the Sanchez just wasn't enough. That's why she got the Alabama Backsplash. It was mother's day after all.
