The correct term for someone who does cosplay. Or at the very least, it means that the person cosplays well.

This usually means that they take part in cosplay groups, do skits to go with their costumes, sew their own costumes, and maybe write a doujinshi on the side. Their costumes generally look better than most cosplayers because they spend more time and more money laying out a pattern and taking the time to do it right.

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.

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