Coonass
Coonass is a controversial epithet used for Cajun people in Louisiana and eastern Texas.
Many Cajuns object to this term, and view it as an ethnic slur, especially when used by non-Cajuns. However, some Cajuns have adopted the term for themselves, and openly use it in jest or to connote in-group pride. 'Coonass' can be seen on t-shirts, caps, and bumper stickers in Acadiana.
Former Louisiana governor Edwin Edwards, himself of Cajun descent, used the word liberally in his campaign appearances.
The origins of 'coonass' are obscure. Some cite the French word "conasse," meaning "dirty whore," as the root of the term. Other scholars believe it is due to Cajuns' supposed proclivity for the hunting or eating of raccoons (raccoons are not part of Cajun cuisine). Another possible source is the racial slur 'coon', used against African-Americans.
