Kangaroo Pouch Surprise

A Kangaroo Pouch Surprise is when you clasp your penis in one hand while the other hand is in the shape of the middle finger gesture. The middle finger pushes down on the head of the penis, causing it to go inside the penile shaft, forming a baggy of skin. Very quickly the middle finger hand pinches off the skin, creating a "kangaroo like pouch". You then proceed to urinate, thus filling up the pouch. When you release your fingers, the urine filled pouch bursts everywhere creating a "surprise" of urine.

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.
