Another term for a hick or a redneck. The term is usually used for high school guys. They tend to wear their Wranglers inside their boots and they are all seen dipping at school at least once. They are also loud, they drink a lot of alcohol, they're wanna be players, and they all drive loud trucks with sound systems. Also, they all have stickers of the rebel flag somewhere on their truck, and they always yell "GIT HER DUN"!!
I went to Walmart the other day and I passed a bunch of kickers that were dipping by their trucks.
