blowass brothers 

Known as "the Jonas brothers" to teenyboppers and older, even more annoying fangirls alike, the blowass brothers are the next big corporate marketing scam by Disney, which will make a massive profit from them and eventually probably take over the world, at this rate. Like every other recent Disney superstar, everybody is talking about how great they are despite their generic musical style. Hopefully in six months no one will remember who they are, but by then Disney will have moved on.

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.
