What the other dude said is what all non-country
people think it is. To pretty much everyone whos country in any way, shape, or form, it more or less means a part of us that does...well, stuff that most people consider country, or old fashioned in some cases.
Anything from having a party by drinking beers out in a (
corn)field with a bunch of trucks, to driving around on back roads with the
windows down, to something as small as asking a girls dad if you can date her before you
ask her out, that way he doesn't blast your ass with a shotgun when you bring her home.
