swanga

Dictionary of American Words And Phrases by John Russell Bartlett.

A word used among the negroes in some parts of the South in connection with buckra, as swanga buckra; meaning a dandy white man, or literally, a dandy devil. Swanga is an African word, and belongs to the language spoken near the Gaboon river, where anything gay or elegant is swanga. The Rev. J. L. Wilson, long a resident in Africa, and acquainted with the language, recognises this word among the Southern negroes.
