break someone's balls
break someone's ballsINFORMAL, VERY RUDE
If a woman breaks a man's balls, she causes trouble for him and makes him lose his confidence. Behind the scenes, this sweet-faced girl was breaking his balls. Note: You can call a woman who behaves in this way a ball-breaker, and describe her behaviour as ball-breaking. Another professor described `Jane Eyre' as a novel written by one sex-starved ball-breaker about another. She worries that people think of her and Jen as ball-breaking, man-hating bitches. Note: These expressions are often used to refer critically to women who seem to enjoy destroying the sexual confidence of men. Note: In this expression, `balls' refers to a man's testicles.
