Blood Rainbow 

Blood rainbows are rainbows that form out of human hatred and dread. They have the appearance of a rainbow at first, but the closer you get, the redder it gets, until it looks like pure blood. Unlike most rainbows, there are ends to these, but at the end of them, there are Death Unicorn dens, and if you get anywhere near those, there is no chance that you'll survive. I implore you not to do it.

"Hey, dude, is it normal for your eyes to be bleeding like that?"
"Oh, absolutely not! I just happened to look at a blood rainbow :)"
"Oh, okay, you're never going to be able to see again! :)"

murdering the rainbow 

Using an excessive variety of colours in Excel.

"So I put the row subtotals in pink on a blue background, these column subtotals in orange on a black background, put the totals in tangerine on a teal background and highlighted the negative values in fuchsia. This should make it really clear to understand. What is your problem?"

"You're murdering the rainbow."

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.

every unicorn will find its rainbow 

A well known phrase that essentially means the same thing as "every giraffe will find their scarf", and "every triceratops will find their berry bush".

Ted: Well you know what they say, Jim. Every unicorn will find its rainbow.
Jim: What the fuck does that even mean, Jim?
