Idiot Radiation

Emanating from exceptionally stupid people Idiot Radiation has the effect of slowly chipping away at a persons intelligence/sanity. Although mild exposure can leave the exposed feeling angry, bitter, and or homicidal for short to moderate periods of time prolonged exposure has been known to increase an individuals resistance, acting as a form of inoculation. (At least in the cases where prolonged exposure hasn’t resulted in violence.)

Idiot Radiation poisoning is common to individuals working in fields that require daily contact with the public.

Effective treatments include: Listening to music, deep breathing, and becoming a hermit. Although alcohol has been known to be an effective treatment, in sufficient quantities it can result in an individual becoming the source of Idiot Radiation and should therefore be considered only as a last resort.

Idiot Radiation tends to effect groups more severely contributing to the ‘mob mentality.’

The only known cure is the complete eradication of the human species.
Dude, must be Idiot Radiation.

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.
