Ryan Pethick Theory 

The Ryan Pethick Theory is an answer to the paradox of quantum superposition better known as "Schrödinger's cat". This theory states the second that the cat (or any other thing) becomes non-observable, it is dead. This theory is based on the not so logical logic that it is much easier to just assume that it's instantaneously dead. You don't have to worry about him, care about him, remember to send a text on his birthday. Basically everything is easier with the assumption that they are dead.
Friend of Ryan #1: "Ryan isn't dead guys he just goes to a different school"
Other Friends of Ryan: "Shut the fuck up... Ryan Pethick Theory."

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.
