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.

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...

Rainbowdash

An awesome pegasus pony from My Little Pony: Friendship is Magic. Her coat is a pale cyan, her eyes are strong rose, her mane and tail are rainbow striped and her Cutie mark is a cloud with a rainbow-colored lightning bolt.

I love Rainbowdash! She is so very rainbow-y!

RainbowDash

RainbowDash is a pony character from the show My Little Pony. In the new generation (My Little Pony: Friendship Is Magic) RainbowDash has a rainbow mane and tail, blue body, blue wings, pink/magenta eyes and has a rainbow thunderbolt coming out of a cloud as a cutie mark. (Cutie Mark-A mark on the pony's 'flank' when they find a special talent they have. Usually gotten at a young age) RainbowDash is famous for being fast, braggy-ish, adventurous. And for her catch fraise "It needs to be about 20% cooler". RainbowDash and her friends are so famous that they take parts in Fanfics such as "Cupcakes", "Rainbow Factory", and "My Little Dashie" (I suggest you don't read Cupcakes or Rainbow Factory, it's a bit gory.)

1. Girl: Who's your favourite pony?
Boy: Fluttershy and Rarity
Girl: That's a shame
Boy: Why?
Girl: RainbowDash is about 20% cooler
