Wikipedia description for this Christmas game.
"Each participant supplies one wrapped gift, usually of similar value.[3] The gifts are placed in a central location, and participants determine in which order they will take turns selecting them. The first person opens a wrapped gift, and the turn ends.[3] On subsequent turns, each person has the choice to either unwrap a new present or to steal another's. When a person's gift is stolen, that person can either choose another wrapped gift to open or can steal from another player.[3] To avoid never-ending circles, each gift can only be stolen twice per game. The game is over when everyone has a present. First player also can steal at the end if desired."
