mofo-ing 

1) Using the word “motherfucker” repeatedly while speaking, usually while shaking your booty, shucking and jiving, high-fiving or slapping your thighs.

In the 2003 HBO comedy show “Tracy Ullman in The Trailer Tails” Tracy plays Ruby, a Hollywood makeup artist. Ruby is doing makeup for Debbie Reynolds and telling her stories while she works. When she tells her about a black actress named Pepper who she used to make up to look white she recalls that the last time she saw Pepper she was looking and acting black again. Ruby offers her services to Pepper and Pepper declines because she is now “openly black” and no longer needs to be made up to look white. Ruby says “she (Pepper) was slapping her thighs and shaking her booty”….”high-fiving and mofo-ing”.

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.
