Flagellation

Flagellation or flogging is the act of methodically beating or whipping (Latin flagellum, "whip") the human body. Specialised implements for it include rods, switches, the cat o' nine tails and the sjambok. Typically, flogging is imposed on an unwilling subject as a punishment; however, it can also be submitted to willingly, or performed on oneself, in religious or sadomasochistic contexts.
