counterflux ventilation 

Ventilation in Victorian chimneys is complicated. The chimney is often interconnected with the other chimneys in the house, meeting at the first floor, rather than at the stack. Because of the presence of dead chimney urchins, the downdraft can impact the convex heat distribution. For this reason, counterflux ventilation is required.

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.
