A fart stainer that stains your pants leaving a brown skid mark,also can be used to abuse somebody
Hey you "Your a fart stainer"

A wet fart slips out by accident you have not followed through but you have just stained your pants with some fart juice.
Can also be mixed up and changed by calling somebody a stain head they will get the drift
