Install CS:S

Word used in the Garry's Mod community (sandbox game). Some custom maps made from players require players to install the game Counter-Strike : Source in order to have the materials and props included in the map. This is because Garry's Mod has a feature that allows you to spawn assets from (some of the) other games that also use the source engine (the same engine Garry's mod uses), so some players create maps that use these assets for players who also has the game required for the map. But this word is now not used since the July 2025 update that made the game include contents from Counter-Strike : Source and Half-Life 2 episodes by default.

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.
