A Dickleback resides on Long Island and drives a giant pick up truck. He sometimes has an American flag or a Trump bumper sticker on there somewhere but is not a requirement. He cuts you off just to end up at the red light with you. When you pull over he is listening to the worst music the radio has to offer at a volume higher than normal ears can handle. He might have a half ass handlebar mustache or a style that should have been terminated for good circa 1986. You may also find a dickleback at a bar or music festival.
another word for two scorchingly hot guys joining forces to slay a large quantity of girls at pyramid rock festival. destoying what was a nice box is now a ten month old snack box from kfc.
