A game, originating in the Midwestern region of the United States, in which participants attempt to photograph one another with their chin on or near the shoulder of an unsuspecting bystander. The quality of a chin is based on proximity to and uniqueness of the person being chinned.
Sally was chinning everyone at the concert last night. She even managed to chin the drummer - wait until you see the album!
