Redneck is a derogatory slang term that was used in reference to poor, uneducated white farmers, especially from the southern United States. It is similar in meaning to cracker (especially regarding Georgia and Florida), hillbilly (especially regarding Appalachia and the Ozarks), and white trash (but without the last term's suggestions of immorality).
In recent decades, the term has expanded its meaning to refer to bigoted, loutish reactionaries who are opposed to modern ways, and has often been used to attack Southern conservatives and racists. At the same time, some Southern whites have reclaimed the word, using it with pride and defiance as a self-identifier.
