When two people talk to eachother spontaneously after a long period of being mad at eachother or something else that doesn't allow the two persons 2 talk to eachother. Refers to how when intelligence vessels are forced to not use their radios so that their position can't be discovered.

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.
