Devil's Fart 

Last fart before a poop. Usually the worst smelling after a long line of farts. The Devil's fart lets you know that if you try to fart again, a poop might come out.

Devils Fart 

When it’s so hot out that you have the worst swamp ass and the gas that’s expelled is so rancid it makes your whiskers curl.

Little Timmy went jogging in the hot summers sun and came home to greet his mom and dad with a devils fart that was so bad she fainted, and the hair on his mustache curled .
