I do hope with trust, no one will be offended, but this people as depicted are very strange with a very detectable dialect that is equally strange. It is then a question of what I had heard some years past of people named as red necks, perhaps these people are what was meant by that term....
This located as term of Red Neck.
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.
