Discordianism
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.

SubGenius, and ha ha only serious.
