An egg with the yolk and white blown out through small holes made in the shell, then filled with depilatory cream and sealed with wax to be used as a projectile.

These are made by sadistic kids around Halloween time. They are quite wicked due to the fact that after being hit by one of these, the chances of washing it off in time before your hair starts to melt are slim to nil. Also- most people react by trying to wipe it off, which further spreads the cream around.
Remember last Halloween when Sarah got hit with that nairbomb? She had a bald spot the size of a grapefruit and wouldn't come to school for a month!

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.
