quux

quux /kwuhks/ n.  [Mythically, from the Latin
   semi-deponent verb quuxo, quuxare, quuxandum iri; noun form
   variously `quux' (plural `quuces', anglicized to `quuxes')
   and `quuxu' (genitive plural is `quuxuum', for four u-letters
   out of seven in all, using up all the `u' letters in Scrabble).]
   1. Originally, a {metasyntactic variable} like {foo} and
   {foobar}.  Invented by Guy Steele for precisely this purpose
   when he was young and naive and not yet interacting with the real
   computing community.  Many people invent such words; this one seems
   simply to have been lucky enough to have spread a little.  In an
   eloquent display of poetic justice, it has returned to the
   originator in the form of a nickname.  2. interj. See {foo};
   however, denotes very little disgust, and is uttered mostly for the
   sake of the sound of it.  3. Guy Steele in his persona as `The
   Great Quux', which is somewhat infamous for light verse and for the
   `Crunchly' cartoons.  4. In some circles, used as a punning
   opposite of `crux'.  "Ah, that's the quux of the matter!"
   implies that the point is *not* crucial (compare {tip of
   the ice-cube}).  5. quuxy: adj. Of or pertaining to a quux.
