Piquerism (derived from the French piquer—"to prick") refers to 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.[1] Piquerism is a paraphilia as well as a form of sadism. The most frequently targeted areas of the body are the breasts, buttocks, and groin.[2]
