furrfu // excl. [Usenet] 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}.
