diparius vassell 

Strange creature of amazingly low intelligence. Lives in a place called whitchurch which is largely made up of mongs and also stinks of shit. Unfortunately diparius vassells are all homosexuals so they will die out within the next century. This will not be a bad thing though because they contribute nothing to the world other than bullshit about bands and songs they like. All in all diparius vassells are smelly cunts who should fuck off immediatley.
Look!!! a diparius vassell lets get away from it, we may catch its mongishness.

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.
