menstrual high-five 

Usually initiated by the guy, an act and symbol of relief that one's lady friend is menstruating and thus, not pregnant. For example, if your girlfriend is on an oral contraceptive and you decide to pull the goalie for the season, one may start to worry that the pill may not be 100% effective. In this instance, one is excited when that time of the month comes and upon hearing of Aunt Flow's visit, a menstrual high-five is warranted.
Guy: hey babe, this party blows. Wanna sneak into the laundry room and fuck on their dryer?

Girl: I can't. I got my period this morning...

Guy: Whew! Menstrual high-five!!!

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.
