(n., from Latin, Dirtus Fartus) a wet fart that soaks cloth, causes horrible rectal itch/burn and occurs when one is not at home and has no means or opportunity to clean up/change trunks.
After John's DIRTFART incident at his mother-in-laws funeral, the family began to rethink his role as a pallbearer.
