Sit up front 

A bathroom prank similar to the Upper Decker, Dry Docker, and Riding the Horse Backwards, but logistically much easier. The idea here is to sit at the very front of the toilet seat, with your rectal opening just over the edge. This way, when you defecate, your feces falls just inside the front lip of the toilet bowl, leaving a brown streak on the side of the bowl. The fecal matter then "welds" to the side of the bowl, outside the water line, leaving a horrible stench and a difficult cleanup job. Because the toilet has not been altered in any way, people may assume that someone just "missed" and was not a deliberate act.

The problem with the "Upper Decker" is that most public toilets do not have an upper tank, and in private residences access to the upper tank is often difficult because of shelving, cabinetry, wall artwork, etc. If there is nothing near the toilet to hold onto, it is also difficult to balance. The problem with the dry docker is access to the shut off valve. In public restrooms this is usually not accessible. Riding the Horse Backwards makes no sense because one would have to remove his/her pants completely in order to straddle the toilet while facing the wall. Sitting up front accomplishes the same goal, but is much easier.

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.
