A nifty little rhyme used by many men to remember the order in which to insert his fingers into his Lady's orifice's.
Shocking = Index and middle finger in the vagina, Little finger in the bum.
Spocking = Index and middle finger in the vagina, Ring finger and little finger in the bum.
The trekkies amongst us will already be masters at 'Spocking'
Guy 1: "Mate, she hated it!! I thought she'd love a good Spocking!!"
Guy 2: "You Gotta Shock her before you spock her!"
Guy 1: "What a nifty little rhyme!!"
