Piquerism (from the French piquer - "to prick") is a sexual interest in penetrating the skin of another person with sharp objects (such as pins, razors, knives, etc). Sometimes, this is serious enough to cause extreme injuries or even death. Piquerism is a paraphilia as well as a form of sadism. The most frequently targeted areas of the body are the breasts, buttocks, or groin.
