Fart Bellows is the opposite of a Dutch Oven. Instead of trapping a person under bed covers after releasing noxious gas fumes from one's ass, the flatulist begins pumping and fanning (expanding and contracting) the bedding covers which expels the gas fumes out from underneath the blankets and sheets into the open air in the bedroom. Person's lying in the bed and anyone entering the bedroom after the fact all fall victim to the fart bellows.

John farted prior to entering the party. He was afraid he would drag it into the party, crop dusting everyone. John quickly performed a fart bellow then confidently entered the residence to join the party.
