Rednecks I know call other people white trash. Often in reference to their perceived drug use. Or to complain about things like having a bunch of broken down cars on their lawn.

It’s a stereotype beyond simply being poor, more or less the same meaning as ‘redneck’ but in a more derogatory way. It usually involves confederate flags (the racism is key), drinking (possibly meth), huge lifted trucks, a love for guns. While ‘rednecks’ often take pride in being redneck, they typically wouldn’t call themselves ‘white trash’ unless they were joking.
