Asininestein 

Someone who thinks he is smart but is actually very stupid. A "know-it-none" as opposed to a "know-it-all". In particular, people who assume their success in one area entitles them to respect in another. (etymology: a portmanteau of the words "asinine" and the name of the bona fide genius "Albert Einstein" - coined by former Jeopardy! writer Ryan Hopak.)
"Glenn Beck spews so much bullshit he's the ultimate asininestein.", "The character Cliff Clavin on the sitcom Cheers was an asininestein."

Word of the Day on October 4, 2026
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.
