A joke religion founded in the late 1950s by Greg Hill (as Malaclypse the Younger) and popularized with the publication of his book (written with Kerry Thornley as Omar Khayyam Ravenhurst) with a book they published in 1965 called Principia Discordia. It is based around the Greek Goddess Eris or Discordia and emphasizes chaos in a sense that has been compared to the movies of the Marx Brothers. For example, all Discordians are considered Popes and schism and disagreement are encouraged.
