placebo effect 

This is mind over matter; when somebody believes that something will happen to his health, it does even when it wouldn't have otherwise. This generally happens when doctors tell patients that their health will improve even though there's no logical reason to believe that; the patients' optimism then helps heal them.
The doctor gave Jimmy sugar capsules and told them it would cure his headaches; it did even though the capsules didn't do anything. Classic placebo effect!

Placebo Day

"Placebo Day" is the unofficial holiday for fans of the rock band Placebo, held annually on 2 May. Its origin lies in a lyric from the band's song "The Bitter End": "We're running out of alibis/On the second of May."

The original group to have started this holiday seems to be the LiveJournal Placebo fan group "placebowhores" (placebowhores.livejournal.com) although it may have originated elsewhere.
"I'm going to listen to 'Nancy Boy' all day long this Placebo Day!"

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.
