What does this mean?!

If you haven't yet seen Double Rainbow, watch it now.

Know Your Meme has this video explaining the history a bit and exploring the spin-offs.

The original video went up back in January, but sat largely dormant. Apparently it started getting hot in the last week or two after Jimmy Kimmel tweeted it on July 3rd.

On GMA a few days ago, Paul Vasquez, the video's creator, alleged: "I mean, there's some other videos on my YouTube page where I was a little high, but not that one."
