Sea Billy's are very much like their sister kissing, 23 and still in 3rd grade, counterparts the Hill-Billy's. Sea Billy's often occupy the small coastal towns as opposed to middle America. Their presence is usually accompanied by banjo music, Keystone Ice cans and underage pregnancy.
Oh, shit. I hear banjos, and there's a pregnant 12 year old. Here come the Sea-Billy's. Lets pay up and go to a different bar. Last time we drink in Shelter Cove, CA

A person that is transient among seaside villages and lives off the ocean. They were never really good at the dirt life. If they could not have the ocean,you could find them in the mountains.
