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.

A female breeder. Short for Moomy, like "Mom" is short for "Mommy." So-called because such women drop offspring like cows do, seeming to have little other purpose in life, and sometimes conspicuously breastfeed them in public. They often also bovinely ignore them...unless you attempt to discourage their crotchfruit from screaming or otherwise misbehaving in public, in which case they will begin lowing like an angry cow whose calf has been threatened.
That stupid Moo was letting her little bastard tear up the entire supermarket while she stood obliviously in the frozen foods aisle.
