Merry Dissmas

From BoardGameGeek:

A rotating Diss-Master reads a card out loud to the group (for example: Who's the worst gift-giver? The chronic over-sharer? The pickiest eater?). Everyone else writes down their answer on their dry-erase boards, and then it's up to the Diss-Master to pick their favorite answer- after reading all the responses out loud, of course!
