Erupting gas exiting the anus violently. It can scratch the anus upon its departure if you decide to trust it.

Series of rapid farts within a short amount of time, thus fore releasing a violent butt scratch. The sound affect is that of a chainsaw, and if hard enough can feel as if a chainsaw is on ur butthole.
“Man, my ass is really itchy, I could really use a nice chainsaw fart right now.”
“They are so satisfying man”

A chainsaw fart is when your ass itches so bad you can’t get to the itch with your fingers so you have those chainsaw farts and the itch goes away in a jiffy.
“Oh man, my ass was itching so bad and when I had one of them chainsaw farts, it knocked the itch right out my ass!”
