gentlesir 

Usually young white beta-males who live on Reddit or 4Chan. They wear fedoras with t-shirts. They open doors for women ("m'lady") or do other nice things not because they're polite people, but because they want to get laid.

Also related: talking about getting friend-zoned, loving V for Vendetta, libertarian politics, thinking they're the smartest person in the chatroom, basement dwelling, etc.
The gentlesir tipped his hat to m'lady and opened the door for her. She was just a random bystander and walked in without acknowledging him. He muttered to himself about how rude women were these days before checking the Reddit thread about anarchism.

The process by which an established, traditionally Jewish neighborhood changes demographically due to an influx of non-Jewish young urban hipsters.

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.
