Double rainbow song

Whoa, that's a full rainbow all the way
Double rainbow, oh my god, double rainbow

It's a double rainbow all the way, damn
It's a double rainbow all the way, damn, oh my god

What does this mean? It's so bright, so vivid
Double rainbow, double rainbow, it's so intense (tense)

What does this mean? It's startin to even look like a triple rainbow
That's a whole rainbow, man, ahhhh

Double rainbow all the way 'cross the sky
Yeah, yeeeeaaaaah, so intense
Double rainbow all the way 'cross the sky
Wow, wow, oh my god, look at that rainbow
