Quoted from LukyDuck:I was curious...Wiki
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.[1][2] Its usage is similar in meaning to cracker (especially regarding Texas, Georgia, and Florida), hillbilly (especially regarding Appalachia and the Ozarks),[3] and white trash (but without the last term's suggestions of immorality).[4][5][6] 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."[7] People from the white South sometimes jocularly call themselves "rednecks" as insider humor.[8]
By the 1970s, the term had become offensive slang, its meaning expanded to include racism, loutishness, and opposition to modern ways.[9]
Patrick Huber, in his monograph A Short History of Redneck: The Fashioning of a Southern White Masculine Identity, emphasized the theme of masculinity in the 20th-century expansion of the term, noting, "The redneck has been stereotyped in the media and popular culture as a poor, dirty, uneducated, and racist Southern white man."[10]
This clarification just confirms my suspicions. "Redneck" as the term is used where I live, refers to working class people from the South. But, it can also be a derogatory term for someone that does something silly or ridiculous. These people normally do not like being called "Hillbillies", as this term is associated with working class people that live in mountainous areas, like Tennessee or other hilly areas North of the Southeast US. There are no mountains or hills for that matter, near my area, so there are no "hillbillies". Although people from the Northeast US usually refer to all people in this class south of their area, as "hillbillies", including people from Florida. I always thought that was strange, because there are no hills in the flatlands... Hence, no "hillbillies" in those areas.
