According to a custom of Christmas cheer, any male and female who meet under a hanging of mistletoe are obliged to kiss. The custom is of Scandinavian origin. It was the plant of peace in Scandinavian antiquity. If enemies met by chance beneath it in a forest, they laid down their arms and maintained a truce until the next day. This ancient Scandinavian custom led to the tradition of kissing under the mistletoe.
