The quiet death of a law through selective non-enforcement. The law remains officially alive in legislation while institutions determine, through omission and unequal enforcement, whose reality the law actually governs.

Coined by Androbeet. Full definition: androbeet.github.io
The law still existed on every official website. It was quoted in speeches and printed in documents. Yet enforcement quietly disappeared whenever a powerful enough person was involved. The law had not been repealed. It had simply stopped functioning. That was nomocide.

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.

I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
