In The Rainbow 

When you and your girl have a threesome with another girl. Then your girl has way more fun than you are with the other girl. Then dumps you for that girl

When Billy laughs at Tom when he got dumped by Becky with his side hoe.
"Ha Ha you've been left In The Rainbow" he laughs out.

Rainbow in me 

It has to do with your body feeling so good from partying hard enough that you feel different, as in you just got wasted from gluttony, hallucinating from strong drugs, or feel your about to pass out/vomit from all that moving around and craziness.

“I feel like I have a rainbow in me from partying hard last night.”
