Coastal Boy: a white male native to the South Carolina Low Country. Coastal Boys are identifiable by their Performance Fishing Gear shirts, visors, and Costa Delmar sunglasses with croakies carefully placed on the back of the neck. The hair of a Coastal Boy is swept down in front and flipped up in the back, thus often confused for a classic Justin Bieber.
