A Marmoset occurs when a woman, angered with her male partner, feigns arousal and informs her partner that she would be incredibly turned on if he were to strip down, stand before her and trim his balls with hair stylist’s scissors, a pair of which she happens to have handy. The partner obliges, and during the course of his trim job, the woman kicks him squarely in the nuts, piercing his scrotum and possibly a testicle.
