Upon sticking your fingers into a bucket of ice/cup of icewater/anything cold, you promptly stick your fingers into a womans anal passageway to the second knuckle.
Kendra asked me for a cup of icewater. I carried the beverage to her with fingers inside the cup(eskimo dipstick prep). Upon handing over said beverage i ninja'd my way behind her and unleashed the cold fingers of fury into her starfish.
Variation: Fingers can then be stuck under the victims nose ala' "dirty sanchez". As the fingers are cold and aroma frozen, this is to be known as the Dirty Inuit.
