When a person holds their farts in all day and their butthole stays tight until it comes time for slumber. Once fast asleep the sphyincter loosens and gas is emitted at high rate of speed for a prolonged period of time
Hey babe when you had a sleep farts last night, your ass hair blew in the wind like a vidal sassoon commercial.

Child: I ALREADY TOLD YOU, I'M EATING WAFFLES!
Farting is a mistake; a sleep fart is a bigger one
