Plastic City 

Los Angeles.

The city synonymous with having a large population of people that are obsessed with their outward appearance.
We're going to the most expensive club in Plastic City tonight, to laugh at all the fake people who lack personality and have perpetual smiles...

Charlotte, N.C.'s big secret is a multi-million dollar love affair with going under the knife. When it comes to this well-hushed reality, this area is second in the country -- second only to "Plastic-City" (Los Angeles) for getting plastic surgery.

Theory of the Plasticity of the Laws of Physics

A theoretical framework proposing that the laws of physics can undergo permanent deformation—that under extreme conditions, they might change in ways that don't revert when conditions normalize. Unlike elasticity (temporary stretching), plasticity implies irreversible transformation: the laws themselves could evolve, learn, or adapt over cosmic time. This theory suggests that the universe's laws might not have been fixed at the Big Bang but might have developed through cosmic history, perhaps through mechanisms analogous to natural selection (universes that produce stable laws persist) or phase transitions (laws crystallizing as the universe cooled). The plasticity of physical laws opens possibilities for cosmic evolution far beyond what traditional physics imagines—a universe whose fundamental rules can change.
Theory of the Plasticity of the Laws of Physics Example: "Her theory of the plasticity of physical laws suggested that the constants we measure today might be different in the distant future—not because anything changes, but because the laws themselves evolve. The universe isn't just unfolding; it's learning new rules."

trucker's tan

I had a trucker's tan after driving for 10 straight hours on a sunny day.

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.
