A surfer who is to lazy to paddle out to the bigger surf. So they ride the small waves near the shore.
**NOTE**: Unless the surf is ONLY breaking at the shore, you are not a sore-shore-surfer.
Guy: Why are you waiting to paddle out?
Me: Gotta wait for this Sore-Shore-Surfer to finish his run.
Guy: Gotta hate them Sore-Shore-Surfers.
