Discordianism: /dis-kor'di-*n-ism/ n. The veneration of Eris,
a.k.a. Discordia; widely popular among hackers. Discordianism was
popularized by Robert Shea and Robert Anton Wilson's novel
"Illuminatus!" as a sort of self-subverting Dada-Zen for
Westerners -- it should on no account be taken seriously but is far
more serious than most jokes. Consider, for example, the Fifth
Commandment of the Pentabarf, from "Principia Discordia": "A
Discordian is Prohibited of Believing What he Reads." Discordianism
is usually connected with an elaborate conspiracy theory/joke
involving millennia-long warfare between the anarcho-surrealist
partisans of Eris and a malevolent, authoritarian secret society
called the Illuminati. See Religion in Appendix B, Church of the
SubGenius, and ha ha only serious.
