Triple Rainbow 

The most completely awe-inspiring and orgasmic experience. Even better than a double rainbow. If you're not seeing triple rainbows, you're just not livin', dude. Paradoxically, if you do see a triple rainbow, the sheer intensity and beauty of it will probably kill you.

It's a full on triple rainbow all the way across the sky.
