I'm thinking of things like general relativity or the Dow Jones Industrial Average. You have a general idea about what context the name belongs to but probably don't understand it well enough to explain what it is to someone else. Is there a word or phrase to express that?

This could include just about anything in the modern-day environment. Apart from an engineer, who can explain how a cell phone or computer or even a TV works? – Cascabel Jul 7 '17 at 16:24

I think jargon is a good one @NVZ! Although I can't explain how it works I can tell you what a cell phone or a TV is or what it does. Does that make sense @Cascabel? – nickflynn Jul 7 '17 at 16:40

I guess it depends on what your idea of "understanding well enough to explain" is. I would not call your examples "jargon". – Cascabel Jul 7 '17 at 17:32

I consider this a better answer than jargon, which is terminology peculiar to a field. General relativity does have jargon such as gravitational lensing but it is the concepts that are difficult rather than the words that express them.
