substrate 

In science a substrate is used as the essential template to grow films with high quality. In a human relationship the substrate will be the person that supports the film in any possible way in the hope to help the film grow to its highest beauty. The substrate and film relationship is non-equal, but forms a connection that is fulfilling in a way unlike any other.
film: I need you, my substrate, in order to grow epitaxial.
substrate: I'll always be here for you, my film! We just need to find the right parameters.

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.
