two police officers in discussion, after one of their fellow officers go off on a foot chase:

officer a): where's my partner Michael?, you seen him?

officer b): i think I saw him on it like a car bonnet, chasing after that hot female teenage delinquent.. (moments later): Tom, here goes the answer to your question, there's Michael, on it like a car bonnet; i don't think we should be disturb him (pointing at a car parked some distance away). He is on it like a bonnet, raping that girl, instead of giving her a hefty fine. I hope they become a cute little couple, lol.

officer a) Thanks man, well looks like that girl didn't have the money to pay the fine anyways, so she got what she deserved. Let's just hope she doesn't have a beautiful disaster. Hang on partner, let me call me my wifey, tell her aqbout Michael and his big fish.

officer b): don't call your wife with such nonsense, you buckwheat brains; she may be on it like a car bonnet, probably playing bingo with her girlfriends or whatever.

on it like a car bonnet 

either

a) for a police officer/detective/Sherlock Holmes or anyone along those lines in hot pursuit of either a of a criminal (usually a juvenile delinquent truating or in search of new adventure (unplanned) in the great outdoor wilderness.

b) can also be used as a derogatory term for a couple who have sex outside in public (usually on the bonnet or hood of their own parked car).

NB: my definition a) comes from the fact that some criminals aressted after a foot chase are brought back to the officer's patrol car/van, physically shoved onto the hood and then handcuffed. Also when people get lost in the wilderness while travelling by car, they might sit on the hood/bonnet of their car and think about what to do, sometimes waiting just long enough for an unplanned adventure to come and find them 9like a bear coming out of the wilderness to smell your vehicle). my definition b) refers to the fact that some couples do use the hood/bonnet of their car to have sex in public, think its okay, simply because its their car.

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.
