Unix weenie
 n.

    [ITS]

    1. A derogatory play on ?Unix wizard?, common among hackers who use Unix by
    necessity but would prefer alternatives. The implication is that although
    the person in question may consider mastery of Unix arcana to be a wizardly
    skill, the only real skill involved is the ability to tolerate (and the bad
    taste to wallow in) the incoherence and needless complexity that is alleged
    to infest many Unix programs. ?This shell script tries to parse its
    arguments in 69 bletcherous ways. It must have been written by a real Unix
    weenie.?

    2. A derogatory term for anyone who engages in uncritical praise of Unix.
    Often appearing in the context ?stupid Unix weenie?. See Weenix, Unix
    conspiracy. See also weenie.
