recursion | = R = | Red Book

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" (though Cygnus people say this is a backronym). See also mung, EMACS.
