factory fart
A person who farts so much, it’s like a factory line, except instead of making cars, they make farts. And they’re really good at it.
My brother farts so fast, it sounds like a machine gun in a cafeteria.
My sister’s fart factory is so loud, the dog ran out of the room.
At the dinner table, my dad farted 10 times in a row like he was doing a job interview.
