The idea of Redneck has been fraught with stereotypes, but a redneck is any relatively right-wing, lower/middle class person living in a rural area who has little or no regard for being overly sophisticated or formal. Contrary to popular belief, a person of any race or ethnic background can be a redneck. The only people who can't be rednecks are metrosexuals, members of overly glamorous subcultures, liberals, and male homosexuals.
Redneck is a subculture, but it's more of an ideology than a style. Thus, a redneck can be part of a second subculture as long as it isn't too glamorous. Subcultural members that can be rednecks include Metalheads, wiggers in some cases, and less fancy-looking punks.
Subcultures that cannot be redneck include Emo, Scene, Goth, the richer looking wiggers, and the more fancy-looking punks.
Common activities that rednecks engage in include hunting, fishing, riding ATVs or dirtbikes, shooting, etc. Pickup trucks are preferable for rednecks, though not essential. The Confederate flag is sometimes used to rednecks not to promote racism, but to promote Confederation, or weaker federal government.
Rednecks are the exact opposite of metrosexuals and city people. They are never afraid to express their views, and aren't afraid to get dirty. They also hate gangsta wannabes and are not intimidated by them.
City Gangsta: I went into the country and tried to steal stuff from this barn, but this redneck came out with a shotgun and told me to get the fuck out. I pulled out my switchblade and showed him my gang tattoos to intimidate him, but he just laughed.
