rumpscare

A play on word jumpscare from horror genre media.

A fart that makes the people who hear it flinch, because it's very loud and came from someone they thought was asleep or didn't know was there.

This is why you should always use your abs and fart as loudly as possible. Accidentally crapping your pants must be an urban legend. It would've happened to me a hundred times by now if it was a real thing.
(Wake up in bed, hear wife nearby on couch, fire off fartillery shell)

Wife: "Omg you scared the baby! He jumped!" (the baby is a cat)
Me: "Oh no!! I'm sorry kitty!!

(after consoling the baby, we realize it was funny, and wife is a Five Nights at Freddy's fan)
Me: "It was a rumpscare"
