Unix weenie
     
         ({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}, {weenie}.
