Sonnet 154 

The little Love-God lying once asleep
Laid by his side his heart-inflaming brand,
Whilst many nymphs that vow'd chaste life to keep
Came tripping by; but in her maiden hand
The fairest votary took up that fire
Which many legions of true hearts had warm'd;
And so the general of hot desire
Was sleeping by a virgin hand disarm'd.
This brand she quenched in a cool well by,
Which from Love's fire took heat perpetual,
Growing a bath and healthful remedy
For men diseased; but I, my mistress' thrall,
Came there for cure, and this by that I prove,
Love's fire heats water, water cools not love.

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.
