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!
