An author named David Duncan wrote a series of books, called A Man of His Word (and A Handful of Men)[0]. Great books.

One of the races in the books was the Anthropophagi (basically modeled on New Guinea headhunters). They talked like that.

You joke, but this is surprisingly close to the name given to Dumbledore in the Dutch translation of Harry Potter.
