Wallshark 

A tenticle-like creature which has a proclivity to violate the rectal region of humans. It has the twin abilities of being able to sense the human butt from long range and the ability of burrowing straight through solid walls made of any material. Very dangerous, but not lethal, the wallshark is able to find anyone anywhere and summarily violate their bottom. The only way to sense their presence is by using advanced precocknition.

There are many variations of wallshark, including the thick and dangerous Euopean, the tiny, but numerous Asian, and the long living African type. With modern trade, it has become very simple for these types to migrate and interbreed. One day we will shall have a super wallshark on our hands with no way to stop it. It will be worse than whales on stiltand a dark day indees.
"look out Jim! It's a wallshark!"

wallhack 

A type of hack used in computer games such as Counter-Strike to exploit the terrain of the arena. Wallhacks come in many forms, but they all are pieces of programming designed to give an unfair advantage to the user, usually a teenage script kiddie. Among known varieties of wallhack are "Ghostmode" (the ability to walk through walls), "Railgunning" (the ability to shoot through walls), "Glassworld" (the ability to see through walls), and many more. Because of the nature of online gaming, it is highly likely that wallhacks will continue to flourish, as for each one found and destroyed, another variation is created.

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.
