A wet juicy fart that occurs after a wet shit that is followed by a thorough wipe. The fart causes the browning of your butt crack and butt cheeks. It leaves a brown film and the remnants of poop directly behind your cornhole. It proceeds to leave skid marks as the the unsuspecting purple traitor has no idea that it leaves the same residue as a wet juicy shit.
That guy smells like shit. He must have just had a butt cheek browner.
