8 bit rainbow 

This is a stage of being high. When you pass your hand slowly in front of your face in a rainbow shaped arc, you should see your hand looking rough around the edges. When you are completely chopped, the roughness will break up your hand into an image skipping across the background. To your mind, it will look like a rainbow rendered in 8 bit detail. Bonus stage! If your hand is made out of stripes of different colors, you are doing something very well.

Extra credit: Watch the video of the double rainbow guy freaking out.

Coloradoian: "Hey man, hit this."

Coloradoian: "Damn son, you be flyin'!"

Memphis Rainbow 

Filling one's anus with skittles and receiving anal sex from an Elvis Impersonator. The resulting mixture of semen, skittle colors, maybe a little blood and hopefully some lube is a 'Memphis Rainbow'

Never blackout on Beale Street or you may wake up to a Memphis rainbow...
She is such a freak, I'd bet she'd taste the Memphis Rainbow

To go rainbow

To go rainbow on something comes from the phrase "colorful language."

It basically means swearing at someone.

I almost went rainbow on some idiot today.

I wanted to go rainbow on that asshole.

ass rainbow 

An imaginary meteorological event occurring after a severe bout of diarrhea, much as a rainbow occurs after a thunderstorm.

"Oh my god, the Kaopectate finally kicked in... I think I've having an ass rainbow."
