casual filter

A part or stage in a game that escalates in difficulty in a very short period of time, separating the casuals from the actual gamers.

Not to be confused with a steep/vertical learning curve, as these mean that the game is hard to learn and master from the beginning.

Games with a casual filter will give you a false feeling of confidence as the filter comes after you have learned the basics and started progressing, just to catch you off guard and make your run end, usually having to start from zero again.

Some examples of casual filters in games include the winter in Project Zomboid and your first goblin raid in Dwarf Fortress
Person 1: Ayo wtf is this I just lost my 30h run, how do you even survive the winter?
Person 2: Welcome to the casual filter, play more and git gud

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.
