adj. A US Navy (and possibly other nations) tradition that occurs when a ship and it's company crosses the equator and the international dateline simultaneously. In doing so, the wog, and even plain shellbacks must go through an initiation process; an accepted form of hazing in todays military. Its should also be noted that when the dateline is crossed, you skip a day. Davey Jones Himself as well as Neptune join in on the fun as well. After all is said and done, a steel beach picnic usually follows this time honored tradition.
sailor #1- "Back in the day, when I was aboard the USS Forrestal during a WESTPAC cruise we obtained our Golden Shellback status."
A term used in todays Navy (US) to describe a well earned "day off" (for those not on duty). The ships usually come to a halt to allow swimming in the waters. Barbeque is abound and in general, good times. Other than the waiting in long lines (aboard an aircraft carrier) these few and far between steel beach picnics are welcomed by even the scurviest of dogs.
sailor #1- "That steel beach picnic was awesome!"
sailor #2- "Don't be an ass, you know some of us were on duty."
