masterblathering 

Excited, pointless and always somehow self-referential verbal-diarrhea. (See ANY Tarantino interview.)
Not an example of usage, examples of actual masterblathering:

"You don't have to tell me how cool I am, listen to ME tell you how cool I am!"

"Did you see me at Madison's party? Everybody was waiting for me to do something cool, I know, but I made them wait until Madison was right next to me. Did you see it? I was SO AWESOME, dude!"

"So I watched this movie once called "City on Fire" at the video store they let me work at and I thought "Shit, nobody's seen this! If I can get Harvey Keitel and that funny-looking guy from Fargo I can totally rip off my first movie!"

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.
