Sensitive Note

Conch is usually a neutral nickname or term of self-reference for any person living in the Florida Keys or the Bahamas, where conch (the flesh of the gastropod) is a popular food. However, the nickname conch is sometimes used with disparaging intent when specifically referring to a person of Bahamian ancestry living in the Florida Keys. And Loyalists who fled to the Bahamas during the Revolutionary War used the nickname conch to refer disparagingly to a native or early settler of the Bahamas.
