What is a common nickname for sailors who have not yet crossed the equator?

The term "Polywog" refers to sailors who have not yet crossed the equator. This nickname originates from the traditional ceremony known as the "Line Crossing Ceremony," which celebrates a sailor's first crossing of the equator. During this ceremony, those who have crossed before, known as "Shellbacks," initiate the Polywogs, or newcomers. The process often involves a series of light-hearted rituals and challenges that the Polywogs must complete to be formally recognized as Shellbacks. This distinction emphasizes the experience and camaraderie among sailors, particularly in naval tradition.

Other options like "Sea Lawyer," "Shellback," and "Old Salt" have distinct meanings within nautical culture. A "Sea Lawyer" usually refers to someone who tries to exploit regulations for personal advantage. "Shellback" is the term for those who have already crossed the equator, while "Old Salt" denotes a sailor with significant experience. These terms reinforce the unique language and traditions of the sailing community and highlight the significance of the equatorial crossing milestone.
