ballbuster 

1) A female who gains power over a male by causing pain to his testicles (commonly "nuts"). Although it can include any kind of "nut" attack. The female most often employs her legs for the task, because of their relative proximity to the groin, and because the legs of a female have the needed stregnth to hurt a male without injuring him.
2) A female who humiliates, belittles, injures, chastises, dihabilitates, or otherwise causes distress to a man through non-physical means.
1) Guys ignore Amy's reputation as a ballbuster when they see her nice legs; at least until she kicks them in the nuts.

2) "That Amy is a real ballbuster; not only did she kick me in the nuts under the table, she used my weakened state to make me agree to her plan."

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
