Rainbowgasm 

Rainbowgasm or Rainbow-gasm is an event where one experiences double-rainbow awesomeness. Despite it's name, it has nothing to do with homosexuality, or sexual pleasure. Though, it has a similar feeling as an orgasm.

Rainbowgasms can occur during a rainbow, double rainbow, or triple rainbow. Other causes include, but are not limited too: Viewing lots of colors at one, listening to techno with colorful flashing lights, or playing with a glass prism.

Dude, check out this double rainbow I saw yesterday.

Ranbowgasm

a series of orgasms in a machine-gun like reaction that can shatter whole terrorist organizations as long as they are stereotypical. Millions of people pay good money to see these. Not to be confused with Rainbowgasm

Maybe if George Bush got a ranbowgasm every once in a while, he wouldn't have to exploit the poor to have a good time.

Rainbowgasm 

to have an orgasm so strong you think you are tripping, have a flashback, have an out-of-body experience, or get possesed by a spirit

I rainbowgasmed so hard it felt like the universe exploded out of my pineal gland and i had to swim through it all to get back to my body...
