Rainbow Rap 

The new gay rap that comes out, and the gay rappers that wear tight pants, clown shoes (dunks), and rainbow-like outfits. Black people who act like they wanna be skaters. Also its not even rap, its a mixture of gayness and r&b. A disgrace to rap.

Kanye West, Dipset, T-Pain, are all rainbow rappers.

double rainbow

A rare type of rainbow that may appear all the way across the sky after a period of rainfall. It can be described as very bright, vivid, and intense. However, many have fallen under the belief that a double rainbow is slowly transforming into a triple rainbow. This is impossible, and is an illusion created by either intense sunlight or a rainbow forming adjacent to the double rainbow.

Double rainbow, oh my god! It's starting to look like a triple rainbow!
