It sounds like some kind of weird tribal chant, but "Bunga Bunga" is a term made popular when 17-year-old Moroccan belly dancer Karima El Mahroug - who calls herself Ruby - said she had attended Bunga Bunga parties at Italian Prime Minister, Silvio Berlusconi's villa in Milan. Allegedly, he got the idea for the parties from the late Mummar al-Gaddafi. Although people disagree on its original meaning, a Bunga Bunga has come to be known as a harem orgy involving a powerful leader. The Bunga Bunga may include hot tubs, stripper poles, skimpy outfits, etc. The usual.
