Spiegelian Logic 

Named for computer science professor and all around cool guy, Dr. Daniel Spiegel, it is the principle in computer science education stating that if something is written, circled, underlined, or otherwise emphasized in the color red, then it is considered to be incorrect within the context of teaching at the time and may never be questioned, lest the questioner be unequivocally annihilated by said cool guy.
"Why is this wrong?" - Dr. Spiegel
"Because it is written in red." - Correct application of Spiegelian Logic, albeit vague

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.
