McGuinty

It East Coast slang for the Shocker. It is the romantic act of inserting two fingers in the Vag, and then slyly sneaking the pinky into the ass to create that romantic moment you have been missing. To perform this procedure properly, your ring finger should be comfortably rested against the taint.

MCGUINNESS

A term derived originating from McGeiver, which was then associated to a one McGruber during the superbowl 2009 Pepsi Cola Commercials in which "McGruber" instead of pulling a McGeiver fails to do so and instead drinks a pepsi Cola. The term was then modified to better suit a more talented individual.

1."I need a credit card, a smoke, and a pen...McGuinness are you buying a bottle of Moet? MCGUINNESS!!!"

2."I need a beard, a paperclip, and Jorge...McGuinness are you trying to get kirk out of his exam? MCGUINNESS!!!"
