A brand of leather flip flops, usually in brown. They are made with a special material so that the wearer's foot molds to it, but unfortunately creates an unattractive footprint (with all the toes).

Rainbows usually cost about $40-50 because of the quality and the brand name. I like to think of them as the Uggs of flip flops.
Reasonably rich person: In the summer, I wear my Rainbows. In the winter, I wear my Uggs.

Other person: Hmm, you have a footprint on your flip flops.

Reasonably rich person: They're not JUST flip flops, they're Rainbows!

(rān′bō′ éd)

When a doof's atmosphere elevates to such an extreme level that it causes the releases of natural endorphins in the brain. These endorphins, combined with the enriched nature of your soul and a mixture of substances as copious as they are numerous, combine into an potent cocktail causing a blissfully euphoric emotional state in which one's identity and conscience merge into the festivals collective-being. Often expressed by dancing.
I was at Rainbow Serpent Festival with the rework crew last year, everyone was so rainbowed.
