Splashkin 

The act of receiving a blow job while discharging a 360 degree watery splash of feces, also known as diarrhea.

Our blumpkin bet quickly quickly turned into a splashkin after the indian buffet at lunch.

Rob: Why do you get so excited when Jessica gives you a splashkin?

Justin: Because if you tilt your hips just right my shit gets sprayed on her face.

Rob: And that turns you on?

Justin: Just marking my property man.
