Norwegian Snow Cone
A modification of the snowballing sex act. Unlike a traditional snowballing job where semen is orally swapped between people, the semen is deposited into a snowball or shaved ice. It is stored for a later time when someone, either unsuspecting or knowledgeable will eat it. Flavors of the snow cone will obviously vary.
Upon learning of Fred's love of shaved ice, his enemy Bill and his girlfriend gave a Norwegian snow cone to Fred. Only after enjoying the "treat" did Bill tell Fred what the secret ingredient was.
