Rumple Butter 

Occurs when small amounts of poop accumulate from not wiping well enough. Eventually the poop hardens into a crust. After an event that causes the individual to perspire the crust melts to form rumple butter. It is distinguishable by its intense odor that may resemble anything from a fresh turd to the bottle return room at your local grocery.
You're playing basketball with some friends and something begins to smell so bad that your gag reflex becomes an unavoidable reaction to the odor. You know that it's not a fart because although a fart may linger for a moment it eventually dissipates. You notice there is no trash or fecal matter present and you begin to deduce that this could be a classic case of rumple butter. Tell your stinky friend to clean their ass out. Rumple butter... Spread that on your toast in the morning... Mmmmm

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.
