The act of obtaining a fireplace bellow and placing inside ones asshole. Then having a spotter pump clean air in the anus to transform the clean air into a false fart. Now with the man filled with fake poop air, he is free to fart wherever and whenever he pleases.

After Frank farted on me i wanted to get him back. After failing to fart on him i decided to enlist the help of my brother in order to perform a chimney fart on Franks dirty jew face.
