face-vasing 

The slang term made up by Daveed Diggs’ character in the movie, “Blindspotting”. This term was made in reference to another characters use of the term “blindspotting” to refer to the “Rubin Vase” optical illusion. This was supposed to remind her of the phrase “belief bias effect”.

His character’s ex, to help her study, would make up slang words/phrases to remind her of the definition of the actual word, etc... “...She still town ...”).

Daveed said “FACEVASIN! Try it out... ‘facevasin’...”

The word she chose was “Blindspotting” because the theory is you cannot perceive both the face and the vase at the same time... essentially relating it to BBE by saying you initially see one side and the other is in your blind spot, perhaps even intentionally.

This is a technique used to gaslight without calling someone crazy. They are simply “blindpotting” you... in other words, “facevasin”.
Face-vasing- defined as the art of intentionally placing people or ideas in a blind spot so as to ignore them.

“Ayo, COLLIN!! As long as that clown is my boss, I’m stuck in this spot, bruh!”

“Damn... you right, Miles. He facevasin’ bad... real bad.”

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.
