golden shellback

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.
