Grim Rainbow 

A "Grim Rainbow" is a term used to describe following a trail which leads to something ultimately pointless, dark, and oftentimes insulting. To follow a Grim Rainbow is to suffer humiliation, and defeat, many times over.

If you believe a Grim Rainbow, then you are suffering from a sad delusion.

"Dude, hearing that Brian Blessed died, only to discover it was a sick joke made me believe in a Grim Rainbow"

hand plant butt sprinkler rainbow

is when someone consumes ten 40 oz bottles of malt liquor, 10 lbs of their favorite laxative, 4 large bricks of cheese, and a variety of different food coloring. This is a stunt that can be done jumping from a trampoline, break dancing, or in vert skateboarding, though it's recommended that a trampoline is used. The tricky part is next as the subject, smashed out of their tree, and completely naked, vaults themself high into mid-air, does a quad flip, double twist, and lands in the hand plant position. Then with a series of violent rotations begins to shit with great force, and a beautiful array of color. Stand back at least 50 feet or so, wear eye protection, and plug your nose when witnessing such an event.

Although that was absolutely disgusting, that hand plant butt sprinkler rainbow was rather impressive. I think that dude needs a nap though now.

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.

douchasserk rainbow 

A combination of douche, asshole, and jerk. When a male person has the qualities of all three, and no other title will describe him. They are colorful in every shade of black and grey. Along with some other undefined colors and random objects, stuck inside their own personal rainbow.

Girl 1: Idek how to describe him. I would say he's a jerk, with a dash of douche, and maybe an even tinier bit of asshole?
Girl 2: Haha, a douchasserk rainbow.

Soggy Rainbow 

When a woman wears different shades of lipstick and a man blows a load on her mouth causing the lipstick to run!

Mary was so horny that she put on every shade of lipstick she had. She called Johnny over and he gave her a soggy rainbow. Mary looked like a sad clown!

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."
