What if you had no real friends at all...
rinsta = real instagram = public, heavily managed to project an image, for acquaintances and others
finsta = fake instagram = private, informal, for real friends

When I was younger, I assumed that old (well, “old”, like 45) people couldn’t figure out how to use technology. So I’d roll my eyes as some adult seemed confused about Facebook or whatever.
Now that I’m aging out of the “young adult” category, I realized I had it wrong: I can still figure out how to use the new hot new social media app, I just don’t see why I should give a damn about any of it.
The sheer fact a 'rinsta' is "heavily managed to project an image" means that it is fake. I guess it's just another example of language evolving counter to logic and original meaning.
