dweeb

   An even lower form of life than the {spod}, found in much the
   same habitat as the former.  though more prevailent on {talker
   systems}.  Unlike spods, upon receiving the desired response
   to the question "Are you male or female?", dweebs will then
   engage upon a detailed description of themselves and how
   wonderful they are, often in the hopes of truly impressing the
   other with their "charm" and "wit".  Nearly all dweebs are
   male, but very few actually live up to the image that they
   present.  Dweebs, unfortunately, are often the cause of
   ill-will, and may well bring a bad reputation to the system in
   question.  They are often, however, easy to wind up and can be
   the source of great mirth to the seasoned user.
