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).
n: The sexual act of taking a popsicle, sticking it in a lady’s anus; inserting your penis inside her vagina and trying to feel the cold popsicle through the perineum membrane.
The act of raising your left 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 reversed (over your left shoulder) whilst riding your illegal Electric Bike faster than the legal speed limit in the UK and triggering a Speed Camera so it captures you Ghost Riding (see Ghost Rider's definitions) and giving the Police "the finger" in the captured Police evidence.
I love to do Ghost Fingering to the Police Gatso Camera when I Ghost Ride past above the legal speed limit on my illegal Electric Bike.
