The Jargon File (version 4.4.7, 29 Dec 2003):

weenie
 n.

    1. [on BBSes] Any of a species of luser resembling a less amusing version
    of B1FF that infests many BBS systems. The typical weenie is a teenage
    boy with poor social skills travelling under a grandiose handle derived
    from fantasy or heavy-metal rock lyrics. Among sysops, the weenie problem
    refers to the marginally literate and profanity-laden flamage weenies
    tend to spew all over a newly-discovered BBS. Compare spod, geek, 
    terminal junkie, warez d00dz.

    2. [among hackers] When used with a qualifier (for example, as in Unix
    weenie, VMS weenie, IBM weenie) this can be either an insult or a term of
    praise, depending on context, tone of voice, and whether or not it is
    applied by a person who considers him or herself to be the same sort of
    weenie. Implies that the weenie has put a major investment of time, effort,
    and concentration into the area indicated; whether this is good or bad
    depends on the hearer's judgment of how the speaker feels about that area.
    See also bigot.

    3. The semicolon character, ; (ASCII 0111011).
