Kersal Massive 

A UK 'rap' group, featuring 'C-Mack', 'Little Fuckin' Kev' and 'Ginger Joe'.

C-Mack lives by the code 'Fuck, peace!', while Little Fuckin' Kev spends his days smokin' da reefer in the corner of various forms of public transport. Buses, trains, planes; you name it, he'll be smoking a reefer in the corner of it. And what of Ginger Joe I hear you ask? He had only this to say: "Yeah man, yeah man." Wise words from a wise man. These guys don't fuck about.
C-Mack: "We know how to do it, Kersal Massive!"

Some one with a very adaptable personality, they can be nice, mean, sexy, corny, boring ,creative, loud, & quiet depending on the situation to reap any and all benefits, a chameleon really, changeable and having many talents. they only show their true colors to those they deem worthy, if you got changed up on, played, or confused its more than likely your own fault, a chameleon changes colors as a defense against predators. they are mostly kind , but don't play yo self there is more than meets the eye with these people an inner strength hidden away from the world avoid ending up on the wrong side of that power and adaptability.

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.

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.
