Line-crossing ceremony

The line-crossing ceremony is an initiation rite in various navies that commemorate a sailor's first crossing of the Equator. The tradition may have originated with ceremonies when passing headlands, and become a "folly" sanctioned as a boost to morale, or have been created as a test for seasoned sailors to ensure their new shipmates were capable of handling long rough times at sea. Sailors who have already crossed the Equator are nicknamed Shellbacks, Trusty Shellbacks, Honorable Shellbacks, or Sons of Neptune. Those who have not crossed are nicknamed Pollywogs, or Slimy Pollywogs; an earlier nickname was griffins.

Equator-crossing ceremonies, typically featuring King Neptune, are also sometimes carried out for passengers' entertainment on civilian ocean liners and cruise ships. They are also performed in the merchant navy and aboard sail training ships.

The two-day event (evening and day) is a ritual in which previously inducted crew members (Trusty Shellbacks) are organized into a "Court of Neptune" to induct the Slimy Pollywogs into "the mysteries of the Deep". Physical hardship, in keeping with the spirit of the initiation, is tolerated, and each Pollywog is expected to endure a standard initiation rite in order to become a Shellback. Depending on the Ocean or Fleet AOR, there can be variations in the rite. Some rites have discussed a role reversal as follows, but this is not always a normal feature, and may be dependent on whether a small number of Shellbacks exist to conduct the initiation.

The transition flows from established order to the controlled "chaos" of the Pollywog Revolt, the beginnings of re-order in the initiation rite as the fewer but experienced enlisted crew converts the Wogs through physical tests, then back to, and thereby affirming, the pre-established order of officers and enlisted.

The eve of the equatorial crossing is called Wog Day and, as with many other night-before rituals, is a mild type of reversal of the day to come. Wogs—all of the uninitiated—are allowed to capture and interrogate any shellbacks they can find (e.g., tying them up, cracking eggs or pouring aftershave lotion on their heads). The wogs are made very aware of the fact that it will be much harder on them if they do anything like this.

After crossing the line, Pollywogs receive subpoenas to appear before King Neptune and his court (usually including his first assistant Davy Jones and her Highness Amphitrite and often various dignitaries, who are all represented by the highest ranking seamen), who officiate at the ceremony, which is often preceded by a beauty contest of men dressing up as women, each department of the ship being required to introduce one contestant in swimsuit drag. Afterwards, some may be "interrogated" by King Neptune and his entourage, and the use of "truth serum" (hot sauce + after shave) and whole uncooked eggs put in the mouth. During the ceremony, the Pollywogs undergo a number of increasingly embarrassing ordeals (wearing clothing inside out and backwards; crawling on hands and knees on nonskid-coated decks; being swatted with short lengths of firehose; being locked in stocks and pillories and pelted with mushy fruit; being locked in a water coffin of salt-water and bright green sea dye (fluorescent sodium salt); crawling through chutes or large tubs of rotting garbage; kissing the Royal Baby's belly coated with axle grease, hair chopping, etc.), largely for the entertainment of the Shellbacks.
