No Pants Friday 

An event that occurs every Friday, regardless of weather, where everyone is required to leave their pants at home for the day. The origins of No Pants Friday (NPF) can be traced back to a cold Canberra night (or two) at Nightsbridge, and first afflicted a group of hearty ANU students. The phenomenon spread like wildfire through the Chemistry department, eventually taking the Fenner school with it. With each Friday, the word spread and more and more men and women join in the NPF festivities.
Mel, it's No Pants Friday, get your pants off and get with the program.

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.
