A religion disguised as a joke disguised as a religion, founded by Malaclypse the Younger (or Mal-2, commonly thought to be an alias of Greg Hill) and Lord Omar Khayyam Ravenhurst (probably Kerry Thornley). Discordians supposedly worship the goddess Eris (or Discordia), but the central theme of Discordianism is a combination of absurdity and philosophy.
Discordians tend to be fun-loving--if eccentric--folks, and great fun to have a few drinks with.
For more information on Discordianism, consult your pineal gland. Or Google it, whatever.
