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.
Someone who is addicted to inhalants. Usually involves a rag soaked with some dangerous chemical and placed in a paper bag to be inhaled. Spray paint is commonly used. Metallic spray paint gives the best results.
"Look at that zombie motherfucker over there with paint on his face. Must be a low-life huffer."
