Arbitrarium 

A museum of the arbitrary.
I want to open an arbitrarium and fill it with things like statues of people who have feet for hands, photographs of people on the beach who went there just because they felt like it, a diorama of a courthouse scene in which a judge is delivering a sentence based on his whim rather than on the facts of the case. A rock from my shoe. A dead squirrel. The letter M. An empty candy wrapper. The sound of silence!

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.
