Bangaversary 

The anniversary of when a couple first banged. Usually celebrated because that is how a couple met and initiated their relationship. The couple may be unclear of when they technically began "dating" so instead, they have to commemorate the first time they began banging. However, a bangaversary is not celebrated upon any two people having sexual intercourse. The initial bang can turn into one of either two scenarios; 1. a one night stand or 2. a steady sexual relationship that may turn into a boyfriend/girlfriend status, in which case a bangaversary is celebrated.
I don't really remember when we became facebook official... so lets just celebrate our bangaversary.

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.
