The phrase "bunga bunga" has become inextricably linked with the private life of Italy's Silvio Berlusconi, and for those who have puzzled over its origins an intriguing new explanation of its meaning has been offered. ... The phrase itself is not new. One of the oldest recorded references dates back to 1910 and another African-themed joke. The infamous Dreadnought hoax was dreamed up by aristocratic joker Horace de Vere Cole, who contacted the British Admiralty pretending to be the Emperor of Abyssinia. He informed officials that he wished to inspect the Home Fleet while on a forthcoming visit to Britain. After enlisting some friends - artists from the Bloomsbury group, including writer Virginia Woolf - to masquerade as his entourage, he turned up at the navy's state-of-the-art ship, the Dreadnought. - John Nixon from Bookmarklet
