c.f. the OSI (7 layer) reference model (physical, link, network, transport, session, presentation, application). "Layer 8" refers to variably the "political", "management", "lawyer", "business", or "money" layer, or some other element the speaker wishes to be denigrate as being technically irrelevant and therefore stupid. Nearly always followed by the word "issues" or "problem".
Not only was the ISO protocol stack technically over-engineered, it became far too embroiled in Layer 8 issues to ever become useful.

Layer 8 Chicken Parm 

In networking terms, the little well-known eighth layer of the OSI reference model.

Layer 8 -> Chicken Parm
Layer 7 -> Application
Layer 6 -> Presentation
Layer 5 -> Session
Layer 4 -> Transport
Layer 3 -> Network
Layer 2 -> Data Link
Layer 1 -> Physical

Normally, during troubleshooting procedures, a problem can be broken down and categorized into one of the lower seven layers. When an issue is of an unknown origin, cannot be resolved, nor can it be explained, it becomes a layer 8 issue, and is pushed aside as unsolvable.

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.
