cock-o-copter 

(v) The act of gripping the base of one's flaccid penis and twirling it around (mimicking the whirling motion of a helicopter blade) when jumping from a tall structure; usu. in an attempt to slow one's descent.

The cock-o-copter is thought to have been invented by Scotsmen in the early 1400's, as an effective method of flying/gliding when combined with the parachute-like properties of their kilts. The overall goal is an effect much like that achieved by modern-day airships (blimps).

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.
