Meinheimer 

A Meinheimer is a bowel movement executed in either a public or shared restroom that is so vile it can only be explained as a fecal holocaust. To qualify as a Meinheimer, one must not only defile the porcelain, the walls and the floor, but the odor must be so foul that it is like getting punched in the face by Mike Tyson in his prime when you enter the restroom and breathe it in. The resulting splatter is characterized by corn, cabbage, nuts and the remnants of a horrific diet. Furthermore, there has been no attempt to either hide the carnage or the stench. Known to induce immediate and profound cases of Tourrete's syndrome in its victims, this abomination was named for Dr. Albert S. Meinheimer of the Nake Gun 2 1/2 film, played by actor Richard Griffiths. A Quantum Meinheimer occurs when one executes this in multiple bathrooms within the same building in a short span of time, thus ruining the lives of all in the vicinity.
"Holy shit! David Meinheimered the first floor bathroom"
"Wrong, he got the second floor as well. That fucker Quantum Meinheimered us!"

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.

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.
