Boarding Up The Closet With Rainbow Corpses 

Someone "boarding up the closet with rainbow corpses" is blatantly homosexual man or woman who tries to hide their gayness through extreme and sometimes violent homophobia rather than coming out of the closet and accepting their sexuality. Derived from the phrase "coming out of the closet" which refers to admitting to the world that you're gay, and to the fact that the rainbow is usually a symbol associated with gayness.

me:"I can't believe Chris! How can he call me a faggot and then threaten to rape me? Isn't that like, the most homosexual threat you can make?"
Seamus:"Dude, chill, he's just boarding up the closet with rainbow corpses. He's more of a fag then you'll ever be."

(editors note:this is based on a real conversation that occured a few times)

colourless rainbow 

utter disappointment, letdown, something insipid.

The football match was a colourless rainbow.

rectal rainbow

When all the diarrhea has poured out of your anus (or whatever orifice it escapes), the butthole makes a promise to never flood your pants again.

I hope a rectal rainbow rescues me from the aftermath of that gas station burrito.

In The Rainbow 

When you and your girl have a threesome with another girl. Then your girl has way more fun than you are with the other girl. Then dumps you for that girl

When Billy laughs at Tom when he got dumped by Becky with his side hoe.
"Ha Ha you've been left In The Rainbow" he laughs out.

Taste the rainbow

Tasting the rainbow

When you eat a full bag of skittles and then let your gf or wife give you a blow job

Then whilst cumming in her mouth you whisper taste the rainbow in her ear

I made Lisa taste the rainbow last night and she loved it

Chilli Rainbow 

Is when a woman is hunched upside down on her shoulders, where she then pisses and shits on to her own face representing the pot of gold. The piss would pan out acting as a rainbow. The logs of soggy poop would soar through the air as if it were chilli.

When President Bush Eats Mexicans He Chilli Rainbows himself asleep. The End.
