"Very online"

I have a very specific image in my head of what "very online" means, but I'm noticing there are other possibilities.

I picture 4chan and memes that make no sense except in terms of five generations of other memes I've never heard of. I picture someone who's into that kind of stuff — the deep lore and history of Internet memes and "meme culture."

On the other hand, this is a very specific picture and I could imagine other possibilities.
