Along the order of a "Belch Wash", "Fart Wash" is the unpleasant odor product of flatulance in the proximity of another person who unknowingly and unavoidably walks through it, smells the sour contents of the belcher's lower intestines and has a negative reaction.
I had been thinking to myself; “Oh Lord! There’s something not right in me”. Between last night’s rich dinner of Halibut & Scotch, the three spicy Bloody Mary’s & beer backers that I drank at brunch with that huge omelet, bacon and hash browns, my ass is on fire. As we walked away from the table, I cautiously expelled a long silent searing hot fart; I still can not believe I did not shit myself! An unsuspecting family of eager diners walking to their seats passed right through my Fart Wash; their facial expressions were priceless. Probably lost their appetite! Nicely played sir!

the stinky wake surrounding someone's fart, in which the farter's unfortunate (or kinky) victim detects the smell; something like standing behind an airplane and detecting the wake of moving air, called prop wash
