antihater 

An antihater is a dumbass who is really obsessed with calling other people "haters" just for the sake of doing it. They will eventually throw insults at these "haters", so basically they are hating on the haters. Therefore, these antihater dumbasses are actually massive hypocrites. Seriously, if you see an actual hater, don't be a stupid antihater and reply with angry messages. Just report or ignore that hater for goodness sake.

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.
