sigma male 

A more internally-focused sibling to the alpha male. While the alpha male quantifies himself on his high position in the social hierarchy, a sigma male prefers to forego the social hierarchy and need for external validation altogether and pursue internal strength instead. Essentially a "loner" or a stray man, although sigma males may have a close circle of friends and loved ones with whom they share a deep connection. The sigma male is not socially inept but simply socially disinterested. Prefers solitary activities where he doesn't have to play social politics and can simply focus on himself. The sigma male accepts that he does not need power over others as the alpha male desires, but rather needs only power to control himself and preserve his own autonomy from others. Sigma males are often pragmatic but may be seen by others as aloof, paranoid, secretive or selfish.

Not to be confused with simply being an unlikeable asshole, edgelord, or misfit.

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.
