The act of a woman shoving a man's head between her breasts and shaking them. Originates from an episode of Seinfeld in which Elaine sent out Christmas cards with out knowing her breast had fallen out of her shirt in the picture. George complains that he had never recieved one, and Elaine procedes to give him a Christmas card.
"You want a Christmas Card? I'll give you a Christmas Card...."
