In Swahili (the lingua franca of East
Africa): someone who wanders without purpose / someone constantly on the move.
It came to be applied to all white
people in East Africa, as most were encountered as traders, visiting colonial officials or tourists.
Today, white tourists are often greeted (especially by
children) with the cry: "Bye bye mzungu!"
For some reason, they rarely say "Hello mzungu!" when they see one coming...
Child: "Bye bye mzungu!"
Indignant white person: "Listen, it'
s 'hello mzungu!' - and anyway, I've lived here for
25 years, you cheeky
devil."
Child: (pause) "Bye bye mzungu!"
or
Ugandan Stall-holder: "A bowl of passion fruit? Um... that'll be 3,000 shillings please."
Indignant white person: "Come again? I'm not paying mzungu prices, I've lived here
25 years!" etc. etc.
