pusfart

The yellowish, translucent jelly like substance in your pant following an early morning fart delivered in a standing position. Volume can vary from a small amount on your finger when probing your anus to check, to approximately 1/2 cup that runs down the back of your leg. Usually only noticed once the pusfart has cooled below body temperature

Very little odor, and not usually offensive

Difficult to remove from pants without wife/girlfriend/partner noticing when doing the washing
