When an illegal drug crew gets a new shipment and/or a new supplier, it is not uncommon for them to have one day where they give out "testers", essentially free samples that junkies will ultimately comment on the quality of. It ensures the dealers or not being ripped off by suppliers and can also cause some junkies to become loyal to that crew and their product. Junkies are often very excited for tester day, since it means a rare free high.
C'mon, we gotta get down to 53rd! The Felson crew is putting out testers today!

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.
