When a female farts and is sitting slightly back enough that the fart bubbles up the front side.
Sometimes it may sound the same as a queef, but it most definitely is not. Usually happens when sitting on a wooden stool or bench. Easier to achieve on a solid surface.
I totally just quarfed. It's came up the front, bubbled on its way up, and tickled a little bit.
A Quarf occures is when a man's is masturbating and beings to make a slimy sound. Mostley happens when he hasnt cleaned off the seemen from the previous masturbation, also known as a Fish Dick (Smelly Dick) which is simalar to Fish Taco (smelly vagina) for women.

joe: how can you tell im stroking softley
bill: well you dick keeps on Quarfing.
