"During the visit to Dreadnought, the visitors had repeatedly shown amazement or appreciation by exclaiming "Bunga! Bunga!".[7] In 1915 during the First World War, HMS Dreadnought rammed and sank a German submarine—the only battleship ever to do so. Among the telegrams of congratulation was one that read "BUNGA BUNGA"."

Berlusconi does seem to have rather ruined (or improved!) that phrase for the rest of us, judging by the Bunga Bunga wikipedia page.
