Knacking 

"knacking"refers to knacker drinking i.e the craze of middle-class Irish teens to go drinking in fields and on beaches."on the knack"is an expression to indicate whether someone decides to "fuck the pub,the owner has enough money" and make like a true viking and go drinking in the wilds.This practice ids highly illegal and half the fun is eluding the "fuzz"(police) and getting pissed for half the price with a perfect view of the sunset.It is also preferable to teens as they have the ability to 'listen to music they actually like' outdoors rather than have to listen to "disco biscuit muzak" in clubs and "mid-life crisis tunes" in pubs"
"hey man,are you heading to the stores(nightclub) tonight?"
"nah,fuck that,man,michael tierney(the owner)has enough money.Me and the lads are going knacking on the beach.We'll get twice as much drink for our money and listen to music that we actually like for a change.Ah,sure,you know yourself it's better to go viking style"

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.
