mumble
 interj.

   1. Said when the correct response is 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 long discussion. "Don't
   you think that we could improve LISP performance by using a hybrid
   reference-count transaction garbage collector, if the cache is big
   enough and there are some extra cache bits for the microcode to use?"
   "Well, mumble ... I'll have to think about it."

   2. [MIT] Expression of not-quite-articulated agreement, often used as
   an informal vote of consensus in a meeting: "So, shall we dike out the
   COBOL emulation?" "Mumble!"

   3. Sometimes used as an expression of disagreement (distinguished from
   sense 2 by tone of voice and other cues). "I think we should buy a
   {{VAX}}." "Mumble!" Common variant: mumble frotz (see {frotz};
   interestingly, one does not say `mumble frobnitz' even though `frotz'
   is short for `frobnitz').

   4. Yet another {metasyntactic variable}, like {foo}.

   5. When used as a question ("Mumble?") means "I didn't understand
   you".

   6. Sometimes used in `public' contexts on-line as a placefiller for
   things one is barred from giving details about. For example, a poster
   with pre-released hardware in his machine might say "Yup, my machine
   now has an extra 16M of memory, thanks to the card I'm testing for
   Mumbleco."

   7. A conversational wild card used to designate something one doesn't
   want to bother spelling out, but which can be {glark}ed from context.
   Compare {blurgle}.

   8. [XEROX PARC] A colloquialism used to suggest that further
   discussion would be fruitless.
