GUBU adj. grotesque, unbelievable, bizarre, unprecedented; (hence) disreputable or scandalous. Also n. and attrib. Etymological Note: The acronym was coined in 1983, based on words spoken by Irish Prime Minister Charles Haughey in 1982, by journalist Conor Cruise O’Brien, who also spared little effort in popularizing it. Originally referring to scandals originating related to the Haughey government, it has since—much like the American Watergate—become a more general term for scandal or political disrepute.
