Service nicknames
Nicknames for the service include The Andrew or Andrew Miller (of uncertain origin, possibly after a zealous press ganger) and The Senior Service. It is also referred to as the Grey Funnel Line: ship owning companies, or lines, painted their steam ship's funnels in distinctive colours such as Cunard's red and black or the eponymous Blue Funnel Line, and the Royal Navy's funnels are plain grey.

Naval salute
Originally subordinates would remove their headgear to a superior. In a book called New Art of War, printed in 1740, it is stated that;

During the age of sail, ships' officers were always worried about mutiny and it therefore became custom that whenever an officer approached, the rating would prove that he was not armed. This was done by knuckling the forehead and later evolved into the modern Navy salute with the hand at 45 degrees, palm facing in. The reason that the palm faces in is because sailors' hands were covered in tar from the sheets and rigging and it was considered unseemly to show an officer or a member of the Royal family a dirty palm.

Toasts

The Toasts of the Royal Navy are a set of traditional drinking toasts.

In June 2013 the Tuesday and Saturday toasts were officially changed under orders from the Second Sea Lord, Vice-Admiral David Steel, to reflect the fact that women have been at sea in the Royal Navy for nearly two decades. Officially the Tuesday toast is now "our sailors" and the Saturday toast is "our families". However, the vast majority of personnel ignore the official change, and use the traditional toasts. 

While most of these toasts are self-explanatory, "a bloody war or a sickly season" refers to the desire and likelihood of being promoted when many people die: during war or sickness.

The toasts are typically given by the youngest officer present at the mess dinner. By tradition, these toasts are proposed immediately after the loyal toast, on the relevant day of the week. The Navy makes the loyal toast seated. This
