My word I've personally used since 1997 to replace 'cool.' They said cool in the 50's and it needs to die. It now just means Okay. Screw that. Awesome and the like are trying to step up, but they don't work for me either.

Jast originally came from the name of an adult japanese rpg company. Their game came on a pirated game cd from Pakistan.
Their logo was a red JAST on a pink ground. A blue haired girl with a fox tail winked at you to the right.
Any celebrity news is not jast.

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.
