Cosplayer 

A shapeshifter who usually takes the form of a fictional character, but can appear in any form. Their most common habitat is in a convention or "con," but can also be found in the wild, although it is rare. They communicate by "junko posing" and although it looks confusing, it can be mastered with observation and practice.

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.

I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
