Bunga bunga words derive from an italian
joke. 3 white
men in an expedition are captured in Africa by a cannibal tribe. The chief tells each one separately: ' You will die, or you will
get our bunga bunga (forced anal intercourse is implied).' The first 2 say they would choose bunga bunga instead of death. The third, being the chief of the expedition, thinks he as dignity to preserve and says he will rather choose death.
The tribe chief says, I admire and
respect your decision, but, anyway, let's do some bunga bunga first!
