Church of the SubGenius
 n.

    A mutant offshoot of Discordianism launched in 1981 as a spoof of
    fundamentalist Christianity by the ?Reverend? Ivan Stang, a brilliant
    satirist with a gift for promotion. Popular among hackers as a rich source
    of bizarre imagery and references such as ?Bob? the divine
    drilling-equipment salesman, the Benevolent Space Xists, and the Stark Fist
    of Removal. Much SubGenius theory is concerned with the acquisition of the
    mystical substance or quality of slack. There is a home page at http://
