The meme to speak about speaking in memes would be to mention: Star Trek, the Darmok episode. Temba, his arms wide.
I watched that episode in the last year and didn't make the meme connection until I was reading someone mention it somewhere. It would be interesting to have a modern take on that episode. The thing with memes is they don't necessarily convey an idea or a point that furthers a discussion. They're often just a way to relate something in the current context with a past idea (for a laugh), so it almost seems that a language based on memes would just end up stagnating culture.
Maybe I should start participating in Star Trek discussions!
