furrfu

( excl.)

   [Usenet;  written,  only  rarely  spoken]  Written-only equivalent of
   "Sheesh!";  it  is, in fact, "sheesh" modified by {rot13}. Evolved in
   mid-1992  as  a  response  to  notably silly postings repeating urban
   myths  on the Usenet newsgroup alt.folklore.urban, after some posters
   complained  that  "Sheesh!"  as  a  response  to  {newbie}s was being
   overused. See also {FOAF}.
