"Krampus is a mythical creature who accompanies Saint Nicholas in various regions of the world during the Christmas season. The word Krampus originates from the Old High German word for claw (Krampen). In the Alpine regions, Krampus is represented by a demon-like creature. While Saint Nicholas gives gifts to good children, the Krampus warns and punishes bad children. Traditionally, young men dress up as the Krampus in the first two weeks of December, particularly in the evening of December 5, and roam the streets frightening children and women with rusty chains and bells. In some rural areas the tradition also includes birching by Krampus, especially of young girls."
