I don't know about that. This sounds more like having a reference and deviations from it.

Whole milk is milk. Milk with the fat removed is fat free milk. Milk with chocolate added is chocolate milk. So you can have fat free chocolate milk defined in terms of what it doesn't have and what it has extra.

Reference LSD causes psychedelic visuals. LSD that doesn't is LSD sans hallucinations. LSD that makes you also taste chocolate in your mouth is chocolate LSD.

Not sure there's a deep observation about culture to be made.
