Shortened nickname for piezo, a glass pipe or tube used for the vaporization & inhalation of methamphetamines. Commonly given clever aliases to disguise the actual purpose of the apparatus such as "Mystic Vase," "Incense Oil Burner," and "Oildale Baby Rattle."
Nate uses the PasserFlyer (TM) to pass the zo full of gerp to fellow gerpadors, thus eliminating the whole "effort" part.
