Jibbery-style oinkery
Jibbery-style oinkery is a phrase coined by Early Cuyler, star of the television show "Squidbillies". To quote Urbandictionary.com, "Jibbery Style Oinkery is symptom that a pig gets when its addicted to meth, and it is Jibbery when its doing Oinkery." To be more accurate, a meth-addicted pig makes a sound called jibbery style oinkery when in the throes of "fixing".
Although associated with drug-addled swine, the sound predates the coining by millennia in human history. Modern techniques using intact ancient thrown pottery and phonograph-like apparati have produced ancient examples of the phenomenon. One recovered artifact from a Mycenaean tomb contained a recording of a Delphic oracle predicting the future outcome of a royal wedding using jibbery style oinkery.
