Perhaps the worst idea for administering drugs since 'hot railing'; a quantity of the powdered drug is placed into the barrel of a cocked air pistol and fired into the rectal cavity, resulting in destruction of the capillary rich rectal lining and consequently immediate absorption. Bioavailability: 95-99%. Also known as 'Prolapse Popping'.
