gangbusters

Gang Busters was a famous radio program that was first heard in 1936 and aired until 1957. The sound effects of police sirens, tommyguns, and screeching tires that opened the show were dramatic and exciting -- this inspired the expression 'coming on like gangbusters'.
Usage has opened up to describe things that are not just exciting, but successful, intense, and many other adjectives, and many drop the 'coming on like' prefix. I think we should be more careful about how we use it, and keep it true to its origin -- something that starts with much excitement and drama is 'coming on like gangbusters'.
The rainstorm late last night came on like gangbusters!

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.
