One who enjoys
smelling farts, either self-flatulated or those
originated from another man or animal.
Fart huffing typically involves a series of deep and aggressive inhalation cycles, sometimes aided by a cupping motion of the palm, fanning the fart from the asshole to the nose.
I was amazed to see Jimmy
huffing his dog's silent farts. He
huffed as if posessed, and it made me
sick to my stomach. I guess Jimmy is a real fart huffer.
