Stupid Flash Bang 

A Flash-Bang is a device used by law enforcement or military personnel to stun people without causing serious injury. Not unlike a firecracker there is no metal or shrapnel that disperses upon explosion. There is simply a loud bang and a large flash of light which disorients any persons within a certain radius. This allows the person(s) utilizing the flash-bang to enter, escape, or take control a situation.

A "STUPID FLASH BANG" is a technique used by person(s) who are being investigated or questioned. Said person(s) repeatedly answer any questions asked of them with nonsensical or meaningless answers. Or in some cases the same answers continuously. The goal being to ultimately cause the accuser or investigator to give up the questioning. And therefore end the investigation, allowing the accused to escape while the investigator tries to fathom how someone could be so stupid or, tries to make sense of the answers which cannot be made sense of at any point.

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.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
