Jack Off Day 

Jack Off day is on the 5th August each day.

Originally coined when an employee added to his calendar that 4th of August was 'Jack Off' day.

Jack off day is a special day of each year that brings joy and happiness to all that follow it. The real magic in Jack Off day is those who do not know about it wouldn't suspect a thing going on.

Followers of twitter tend to tweet with the tag:
#jackoffday2010
#jackoffday2011
etc

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.
