Prefab-Con 

In construction, a prefabricated house is produced in a factory, shipped out to building sites, and assembled by folks unequipped to design anything better. The prefab conservative, or prefab-con, brings the same attitude to political discourse: rather than using reason and critical thinking to craft arguments that fit the real world, he trots out prefabricated memes, arguments and conclusions that are passably functional at best. All too often, they are even worse: the typical prefabcon lives in an intellectual house of ugly, wobbly walls that collapse on themselves in slight gusts. Undaunted, he throws up another structure on the same spot, though that wolf named reality is standing right there, ready to huff and puff again.
Our generation has witnessed several prefab-cons, including, but not limited to, Sarah Palin and John McCain.

More from Urban Dictionary
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.
