Hare Hare Yukai 

Literally translated as "Sunny Sunny Happiness", Hare Hare Yukai is the name of a popular dance that stemmed from the Japanese animated series "The Melancholy of Haruhi Suzumiya". Since its posting on Youtube, hundreds of parodies and performances have sprung up on the website from countries around the world, making it one of the most popular dances ever. One video shows hundreds, perhaps thousands of Japanese cosplayers blocking an entire street to perform the dance shortly before they are dispersed by the presence of Tokyo Police.
Damn! Hare Hare Yukai is hard to learn... But it's so much fun, and it's worth it!

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.
