there is a difference between redneckish ways and "white trash"
Of course there is.
One can be "redneck" without being trashy.
One can be trashy without being redneck.
However if you take your standard non-trashy redneck and make him a white trash redneck, you end up with an incredible combination of beer gut, sleeveless shirts, massive beer consumption, the attitude of a boar hog, the smell of a billy goat, the IQ of a gar fish, the work ethic of a 12 year old call of duty addict, without a doubt standing in a puddle of his own dip spit while crashing into people and yelling "PLAY FREE BIRD MOTHER frickERS"
