catsitting 

An often occurring event when Skidoo riders, out of charity, allow cat riders to ride with them. After a rip through the woods, the Doo riders will invariably be forced to wait for the cat riders to catch up. More often than not, the cat riders never show up due to mechanical failure of their inferior sleds. Hence, the term catsitting refers to Doo riders sitting and waiting on cat riders.
We went rippin with Arctic Cat Dave in Cherry Creek, but ended up catsitting most of the weekend.

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.
