dump scare 

when you shit in the toilet and the toilet water splashes back at you.

You’re sitting in the Sonic bathroom, after a lovely chili cheese dog. There’s a line outside that’s been there for about 20 minutes because you’ve been busy on the toilet. You’re finally done with your business, and you have one more shit to plop out. You let it out, but it is a small one. It hits the water, and you feel the cold water splash up and hit you, also called a dump scare.

Dumpscare 

1. The fear associated with a potential shart.
2. Any unexpected shit- and/or fart-related event that can be described as a jumpscare.

Two buddies after Chipotle:
quiet flatulence, followed by a prominent wetness
"Hey, man, what happened? You look stressed."
"Dumpscare."
