Slang term for the underground practice of inhaling vapor from
human feces, primarily for the narcotic effect of its methanethiol
gas combined with the effect of hyperventilation. The term itself comes from "turd" and "huffing" due to the rapid inhalation and exhalation from paper or
plastic bags containing the fecal matter. As with
glue sniffing or hallucinogenic mushroom consumption,very unpleasant symptoms are experienced prior to the high, slowing the spread of the behavior. While its high is considered uniquely euphoric, tuffing is relatively brief and those who indulge in the practice risk severe infection, irritation of eyes and mucous membranes, convulsions or in extreme cases, coma or death.
