A fart possesing the same physical properties of a regular fart with an abundance of moisture (usually sweat). This results in a more audibly defined crackling sound as opposed to the muffled rumblings of the common rip. May sound like a shart, however wet-farts do not include a follow thru.
Tom: "gross man, did you just shart?"
Jerry: "relax, it was just a wet-fart."
Tom: "oh. pass the funions."
The ultimate in flatulence... it is when not only gas is passed through your grocery hole, but a small mixture of juice from the colon comes out with it, producing a wet sound and a lingering nasty stench that one can be proud of. Just make sure to go right to the bathroom and give yourself a good wipe after the fact...it is preventative to the itching and chaffing that will occur, also you may need to change your underware so use caution.
Dude... my girlfriend took a whiff of my wet fart and started blowing chucks out the car window!! How sweet is that?
