recursive acronym

recursive acronym: n.  A hackish (and especially MIT)
   tradition is to choose acronyms/abbreviations that refer humorously
   to themselves or to other acronyms/abbreviations.  The classic
   examples were two MIT editors called EINE ("EINE Is Not EMACS")
   and ZWEI ("ZWEI Was EINE Initially").  More recently, there is a
   Scheme compiler called LIAR (Liar Imitates Apply Recursively), and
   {GNU} (q.v., sense 1) stands for "GNU's Not UNIX!" -- and a
   company with the name CYGNUS, which expands to "Cygnus, Your GNU
   Support".  See also {mung}, {EMACS}.
