A fartwraith is similar to a fart ghost, though far more dreadful. While a fart ghost would linger in a room like a group of scene kids behind the local 7/11, a fartwraith is birthed like a mammal from the ass and permeates the fabric of your underwear and pants. These babies set up camp for the long haul. Fartwraiths could even persist after a run through the washer and dryer. You'll be hard-pressed to believe it wasn't a shart. Your best bets are to either bleach your cursed linens, or empty an entire can of Lysol into the ground zero anal regions.

Can also be used as a generic, vulgar epithet which is typically applied to persons who are lazy, daft, and/or bootlickers.
