I grew up in a family that loves quotes and pop culture references. Half of them I had no idea what they were or where they were from. Some I still don't. But if someone said it to me, I'd know exactly what they meant. And if I said it to someone outside my family... blank stares
I have always felt that the "Darmok and Jalad at Tanagra" language is impossible. Among other things, there is no way for it to be passed down without more general language in which the specific events can be described. There is a lesson in that for those who disdain abstraction.
