Redneck is a derogatory term chiefly, but not exclusively, applied to white Americans perceived to be crass and unsophisticated, closely associated with rural whites of the Southern United States. Its usage is similar in meaning to cracker, hillbilly, and white trash. In Britain the Cambridge Dictionary definition states: "a poor, white person without education, esp. one living in the countryside in the southern US, who is believed to have prejudiced ideas and beliefs. This word is usually considered offensive." People from the white South sometimes jocularly call themselves "rednecks" as insider humor.
