The act of coitus interruptus followed by urination, i.e. pulling out early, cumming on a female's stomach, then immediately
pissing whilst the penis is still erect, such that both fluids form a rainbow-like arc.
After six King Cobras and already breaking seal, I couldn't hold my piss in anymore, so I figured I'd give my girl a double rainbow. She was so happy she cried 'Double rainbow all the way, what does this mean!?!'

An innuendo for multiple orgasm. As made famous by youtube actress Ceciley's verbatim, passionate interpretation of Hungrybear9562's viral video "Double Rainbow" In which she sounds like she is having multiple orgasms.

Pure unequivocal elation at seeing two of anything, particularly rainbows. Originated from a youtube video (search for Yosemitebear Mountain Giant Double Rainbow) where a man is so incredibly taken aback by seeing two, almost three rainbows!

He then proceeds to cry from happiness, as you too would do if you were there.
