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.

Urg. I just had a rainbow-gasm.


Omg dude check out my new colorful banner.

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...
