Avery Old Coyote, of the Flathead Reservation in the U.S., was playing a round of Cards Against Humanity with some friends when inspiration struck.
The game has been dubbed "the party game for horrible people" and it's easy to play. Each round, a player draws a black card with a question or phrase. Then, the other players select their craziest or most hilarious white card to go along with it. The player who gets the best reaction wins that round.
