Batafloni or "μπαταφλόνι" is a special purpose table specifically designed to accommodate the backgammon needs of a sailing vessel. Most bataflonies are typically located at the stern of a ship and are made of wood. Like most tables that are onboard vessels, the batafloni is a fixed table and it cannot be moved. The top of the batafloni has engraved in it the backgammon design so sailors during high seas can continue playing backgammon.
The angry man, swept all the backgammon pieces from the batafloni to the ground.

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.
