In existence for over 400 years, the Royal Navy is the world's oldest fighting force and in that time has added to the richness of the English language with the use of slang terms otherwise known as Jackspeak.
For example, have you wondered where the term "taking a long shot" came from? Today it means trying something that stands little chance of succeeding and it originated from firing a cannon outside it's normal range in the hope of getting a lucky hit.
As an ex-sailor myself, I went to sea with the "Grey Funnel Line", otherwise known as the Royal Navy, and during my sea-time often came into contact with "Pickle Jar Officers", namely officers with a university degree who could tell you the square root of a pickle jar lid to three decimal places, but couldn't get the same lid off.
People who want an easy life are said to be "swinging the lead" and this arose from sailors dropping a lead weight on a line to measure the depth of the sea in shallow waters - it was a popular task because it was an easy way of avoiding real work at sea.
Some terms I remember from my time in the Royal Navy include:
Scrub Round - cancelling an event.
Hammy Cheesy Eggy Topsides - a toasted ham and cheese sandwich topped with a fried egg.
Airy Fairy - a naval rating who served with the Royal Navy's Fleet Air Arm.
Bombhead - a naval aircraft armourer.
Buckets of Sunshine - nuclear weapons.
Helioproctosis - a condition that makes people think the sun shines out of their backsides.
Going Harpic - someone who was clean round the bend.
Order of the Golden Toecap - redundancy, also known as "the boot".
Chewing the Fat - relates to the fact that tough beef soaked in brine had to be chewed for a long time to make it easier to digest.
Crash Out - go to sleep after a run ashore.
Duty Beauty - a rating who is on watch.
Gobbling Rods - dining utensils.
Mudhook - ship's anchor.
War Canoe - a large warship such as an aircraft carrier.
Paraffin Pigeon - helicopter.
Sweating Neaters - to be very worried about a forthcoming event.
