RFC 3092                   Etymology of "Foo"               1 April 2001


   Section 2 below describes the definition and etymology of these words
   and Section 3 interprets them as acronyms.

   As an Appendix, we include a table of RFC occurrences of these words
   as metasyntactic variables.

2. Definition and Etymology

   bar /bar/ n. [JARGON]

   1. The second metasyntactic variable, after foo and before baz.
      "Suppose we have two functions: FOO and BAR.  FOO calls BAR...."

   2. Often appended to foo to produce foobar.

   foo /foo/

   1. interj.  Term of disgust.

   2. Used very generally as a sample name for absolutely anything, esp.
      programs and files (esp. scratch files).

   3. First on the standard list of metasyntactic variables used in
      syntax examples (bar, baz, qux, quux, corge, grault, garply,
      waldo, fred, plugh, xyzzy, thud). [JARGON]

      When used in connection with `bar' it is generally traced to the
      WW II era Army slang acronym FUBAR (`Fucked Up Beyond All
      Repair'), later modified to foobar.  Early versions of the Jargon
      File [JARGON] interpreted this change as a post-war
      bowdlerization, but it now seems more likely that FUBAR was itself
      a derivative of `foo' perhaps influenced by German `furchtbar'
      (terrible) - `foobar' may actually have been the original form.

      For, it seems, the word `foo' itself had an immediate prewar
      history in comic strips and cartoons.  In the 1938 Warner Brothers
      cartoon directed by Robert Clampett, "The Daffy Doc", a very early
      version of Daffy Duck holds up a sign saying "SILENCE IS FOO!"
      `FOO' and `BAR' also occurred in Walt Kelly's "Pogo" strips.  The
      earliest documented uses were in the surrealist "Smokey Stover"
      comic strip by Bill Holman about a fireman.  This comic strip
      appeared in various American comics including "Everybody's"
      between about 1930 and 1952.  It frequently included the word
      "FOO" on license plates of cars, in nonsense sayings in the
      background of some frames such as "He who foos last foos best" or
      "Many smoke but foo men chew", and had Smokey say "Where there's
      foo, there's fire".  Bill Holman, the author of the strip, filled
      it with odd jokes and personal contrivances, including other
