Metallic Rainbow

A rainbow lacking in color and presented in greyscale.

When displayed it can take on a few meanings:
1. An open statement of one's heterosexuality.
2. Having Anti-Homosexual sentiment.
3. A fan of the Metal genre of music.
4. In protest against the use of the rainbow as a homosexual symbol.
5. Replacement for non-homosexual emblems, labels, signs or etc. that feature a colored rainbow, as to avoid confusion.

Straightened the Rainbow

1. When her booty so fat, pussy ain't flat, and titties where it's at, it can make a gay man's dick say, "Hello!"

2. When his stomach so flat, his dick's a bat, and he shaved his mat, it can make a lesbian's pussy go "splat."

1. When Drake saw a real woman for the first time, it straightened the rainbow. So he went and dumped his boyfriend Hailey.

2. When Michelle caught a glimpse of David's long dong, it straight up straightened the rainbow. So she went and dumped her girlfriend Claudia.
