A redneck metrosexual, one whose personal image projects sensitivity, soulfulness, refinement, and a willingness to pay attention to a lady's deepest needs. A blue-stater whose sense of personal style would probably get him beaten up in a typical redneck bar. A strain of southern masculinity which runs counter to the NASCAR-watching, Jack Daniels-swilling, wife-beating, trailer park-living stereotype.

If the Bee Gees had a little twang, they'd be superb Jethrosexuals.
