A rare and expensive drug found in Cambridge, Massachusetts, distributed by the being known only as Dr. PrepStone aka the Pterodactyl. It is basically ground up cow utter which, when smoked, releases all of the cow's hormones in addition to its remaining milk. It can cause anything from hallucination to seizures.
It was originally discovered by British Prime Minister Winston Churchill, who created it in an experiment alongside Bono's grandfather, Bono. Its full potential was not known until along came a Vietnamese doctor named Timbuk the Second, commonly written as Timbuk II. Warning: can cause induced menstrual cycle in male users.
