	FOO?	A greeting, also meaning R U THERE?  Often used in the

FOO 1. [from Yiddish "feh" or the Anglo-Saxon "fooey!"] interj. Term
   of disgust.  2. [from FUBAR (Fucked Up Beyond All Recognition),
   from WWII, often seen as FOOBAR] Name used for temporary programs,
   or samples of three-letter names.  Other similar words are BAR, BAZ
   (Stanford corruption of BAR), and rarely RAG.  These have been used
   in Pogo as well.  3. Used very generally as a sample name for
   absolutely anything.  The old `Smokey Stover' comic strips often
   included the word FOO, in particular on license plates of cars.
   MOBY FOO: See MOBY.

BAR 1. The second metasyntactic variable, after FOO.  "Suppose we have
   two functions FOO and BAR.  FOO calls BAR..."  2. Often appended to
   FOO to produce FOOBAR.



MUMBLE interj. 1. Said when the correct response is either too
   complicated to enunciate or the speaker has not thought it out.
   Often prefaces a longer answer, or indicates a general reluctance
   to get into a big long discussion.  "Well, mumble."  2. Sometimes
   used as an expression of disagreement.  "I think we should buy it."
   "Mumble!"  Common variant: MUMBLE FROTZ.  3. Yet another
   metasyntactic variable, like FOO.
