royal wave 

The type of the hand gesture that royalty (for eg Queen Elizabeth II) gives when passing a crowd, normally from inside an expensive vehicle or on top of a horse drawn carriage. Similar to parade wave but with even less effort required, since everyone is already looking at royalty, there's no need to get their attention with large gestures.

It can be used by non-royalty to wave to a group of friends while a passenger in a car leaving a carpark or street, where it is normally intended as humor.

"I gave them the royal wave."

Royal Wave 

The art of sexually stimulating a woman with one's entire hand using a motion similar to that of the British Queen's famous wave. This technique is primarily used for women of the 'looser' variety, i.e those with a sizeable 'welly boot top'.

"Man, I was giving her the royal wave last night and I swear I still didn't hit the sides".

Royal Finger Wave 

The act of a member of the Royal Family waving at a member of the public but not in a Royal style (hand rotating in a forward direction with fingers fixed at a horizontal angle) but with their hand and fingers pointing to the person and them moving their fingers up and down in a friendly manner just like they are waving at an acquaintance.

In 1982 the Queen Mum waved at me with a Royal Finger Wave and not the usual Royal Wave whilst I crossed a bridge over the River Thames in London with my father.
