1. A redneck who is not even redneck enough to drive a pickup truck. Instead he or she drives a low-end American-made sedan, usually a Dodge Neon, Chevy Malibu or other equivalent type.
2. A lower class among hicks. Not a true redneck enough to hold a manual-labor job, so does not drive a pickup truck like normal rednecks.
There was a traffic jam of sedan rednecks outside of Wal-Mart today during the lunch break.
