Ghost Finger Wave

The act of using your right arm and extending your middle finger as in "the finger" or the middle finger (as in giving someone the (middle) finger or the bird or flipping someone off) as an obscene hand gesture but staying at a horizontal angle (much like a Sieg Heil but winding in and out your middle finger keeping your other fingers closed) whilst Ghost Riding past people and Police on your illegal Electric Bike thus giving the Police "the finger" Ghost style not like the Queen Mother who did this with all four fingers (Royal Finger Wave).
