PoB

   <humour> (PoB) A derisory term, in use generally among {Unix}
   users, for anyone who uses {Microsoft} products either because
   they don't know there is anything better (i.e. Unix) or
   because they would be incapable of working anything more
   complex (i.e. Unix).

   The interesting and widespread presumption among users of the
   term is that (at least at the time of writing, 1998) using
   anything other than Unix or a Microsoft OS (whether {VMS},
   {Macintosh}, {Amiga}) is so eccentric a choice as to be at
   least somewhat praiseworthy.
