PARIS: Pack your chastity belt, Gilmore – you’re going to Harvard!
A chastity belt is a locking item of clothing designed to prevent sexual intercourse or masturbation. Such belts were historically designed for women, ostensibly for the purpose of chastity, to protect women from rape or to dissuade women and their potential sexual partners from sexual temptation. Use is mentioned from the Renaissance, but in such a way that it might have been a joke, and there’s a good chance some chastity belts from the past are actually fakes. They were typically used in the 19th century by women as anti-rape devices.
