(s)ex dream 

An extremely awkward form of sex dream where the dream-partner in question is an ex-lover.

Unlike normal sex dreams involving your current partner, or a random friend/acquaintance, (s)ex dreams are disturbing because you KNOW what the sex with that person is like (and so the dream is more realistic), but have valid reasons why you are no longer with them.

General feelings upon waking include: feeling dirty and ashamed, horniness, guilt, nausea and confusion. These feelings are amplified if you found yourself enjoying the experience.

Even more awkward when you are in bed with your current partner and you have a (s)ex dream.
I had a (s)ex dream about my old girlfriend, Claire, but I woke up feeling really guilty because I was in bed with my wife.

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.
