Pafart
A pafart is a fart that starts gentle, like it’s testing the waters, but then it gets real messy and real loud.
My pafart started like a little fart, then it got loud enough to make my dog run out of the room.
I was in class and my pafart came out like a little fart, then it turned into a big one that made my teacher turn around.
I was trying to sleep, but my pafart started soft, then it went full-on scream and woke me up.
