when you are sitting on the toilet taking a dump while getting a blowjob... and right before you bust a load you drop a huge dump and the water from the toilet and ur jizz hits the girl in the face at the same time

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.

A phenomenon that occurs when a man pulls out to ejaculate, but doesn’t clean all the semen off the tío of his penis. When he goes back in for round 2, there is a little semen left that gets the girl pregnant, thus creating a backsplash baby.
Dude 1: I got her pregnant again man. But I could’ve swore I pulled out.
Dude 2: Did you go back in for round 2?
Dude 1: Duh.
Dude 2: Raw?
Dude 1: Duh.
Dude 2: Lol. Then it’s probably a backsplash baby.
