In 3d modeling, these are modular assemblies of small detail models applied to the surface of larger models to add visual interest/complexity to otherwise plain areas. The detail models are generally designed to look like they serve some sort of mechanical/technological function, although what said function is specifically is typically ambiguous.

The term dates back to at least the 1970s, when it was used among cinematic special effects artists to refer to physical models used in the same way in the construction of props and miniatures. At that time, they were often made from kitbashed hobby models of battleships, tanks, and cars.

Today, the term usually refers to digital 3d models of this nature, which are created in the same manner as any other 3d model, but reused repeatedly to speed up the process of creating subsequent models.

It can also be used as a verb to describe the act of applying nurnies.
The Death Star, when shown up close, is covered in nurnies. That's no moon. It's like 1000 hours worth of pieces of plastic boat.

I don't want to design any spaceships today, so I say for these Star Destroyers, we nurnie these enormous arrow shaped piece of foamcore. Who's with me?

That robot looks cool, but it doesn't seem technologically complex enough. Nurnie it up, buttercup.

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.
