"Oh man, that boxer is such a NilKO; he always goes down on the first round without even putting up a fight!"
"Playing Grand Theft Auto: San Andreas for the first time will have u feelin' like such a NilKO... it's impossible to win"

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.
