Lisu people
According to James A. Matisoff, who introduced the term "autonym" into linguistics: "Human nature being what it is, exonyms are liable to be pejorative rather than complimentary, especially where there is a real or fancied difference in cultural level between the ingroup and the outgroup." For example, Matisoff notes, "an opprobrious term indicating mixed race or parentage" is the Palaung name for Jingpo people and the Jingpo name for Chin people; both the Jingpo and Burmese use the Chinese word ("") as the name for Lisu people.
