Dirty fart

When you go to take a shit and all that comes out is a fart that makes your cheeks wet. Toilet is clear, but the TP is as brown as a bear. Not to be confused with a shart which does in fact provide some goods.
Note: If your bear is white - you are wiping the wrong hole.

Just sat down for a shit but it was only a Dirty fart.

DirtFart 

(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.
