casino air 

Term based on the myth that Vegas hotels pump extra oxygen into their casinos to keep people awake, boost alcohol's effects, etc. etc. This is false, and would be highly illegal if true. Not to mention what would happen if someone lit a cigarette.

The "rush" that many people feel when entering a casino is really a combination of overstimulation (flashing lights, noise, excitement) and sudden exposure to lower temperatures; though they aren't allowed to pump oxygen in, some casinos keep temperatures lower than normal to help keep people awake and alert, spending more money rather than returning to their rooms.

Although it's based on false information, the term is not obsolete; it can also refer to the casino's atmosphere of excitement and risk.
In Vegas, the casino air can hit you as soon as you step off the plane.

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.

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.
