shellbacks

Crossed the equator

Shellbacks are sailors who have crossed the equator, distinguished from pollywogs who haven't.

The term comes from naval tradition where first-time crossers undergo an initiation ceremony, emerging as shellbacks—tough and seasoned like a turtle's shell.

The shellbacks hazed the pollywogs mercilessly during the crossing-the-line ceremony.

The word suggests nautical experience and endurance.
