Shakeweight 

Not to be confused with the vibrator, I mean dildo, I mean workout assistant, shakeweight refers to the excess ground marijuana that's left in the grinder because it won't fit into the fatty when rolling a joint.

Shakeweight only accumulates when a gross overestimation was made, resulting in excess ground weed left in the grinder that can't fit into the joint.

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.
