“Redneck is a historically derogatory slang term used in reference to poor white farmers in the Southern United States. It is similar in meaning to cracker (especially regarding Georgia and Alabama), hillbilly (especially regarding Appalachia and the Ozarks), and white trash (but without the last term's suggestions of immorality).
