Castrato 

In the early days of opera, womyn were not allowed to sing in public, not even in a chorus. How to fill in the female roles in opera? Pick a choir-boy with a great voice that has not yet deepened, by consent of their parents, perform a little operation on them, removing the testicles.

Results? Without the hormones needed for adulthood, their voices remained sopranos and altos while their chests and lungs matured regularly, their voices combined male power with female beauty. Now they were able to successfully pull off female roles onstage.

Today, this practice is illegal.

Literally: to accidentally blast one's own genitalia off via a negligent discharge of a firearm that is being "carried Mexican."
Mexican castration almost happened to Plaxico Burress when his (.40 S&W) Glock 23 went off and struck him in the thigh at that New York night club because he had his piece tucked into the waistband of his sweatpants. But seriously, despite the fact that he could have shot his own balls off, who wears sweatpants to a nightclub?

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.
