Just like a double rainbow, only with half the rainbow, half the tears, and half the intense orgasm. Also known as a "rainbow". When people see a single rainbow, they don't start crying or singing, but instead go "hey look a rainbow" and then continue on with their lives.
Person 1: single rainbow all the way, across the sky... YEAAH-
Person 2: It doesn't work like that...
