Jersey Shore slang for a person who travels to the beach for one day. The phrase started in the days when people would bring their lunch to the beach in a shoe box. Hence, Shoe-B(e). The phrase is used by locals in a derogatory manner toward anyone who has to drive to the shore; especially Pennsylvanians and New Yorkers.
The beach is crowded today. I wish the Shoe-Bes would go back to where they came from.
