A more advanced practitioner of the art of ballbusting. A woman who lives to demean men, to figuratively crush their testicles into a fine powder so that the wind can disperse it and leave no trace that the man ever had any testicles.
A ball crusher is a device made from either metal or often clear acrylic that squeezes the testicles slowly by turning a nut or screw. How tight it is clamped depends on the pain tolerance of the person it is used on. A ball crusher is often combined with bondage, either with a partner or by oneself.
