Rainblowjob

When the girl puts a drop of food coloring of each color on her tongue and gives the guy head. When he comes in her mouth, she mixes it in her mouth and spits out a rainbow.

Dude I found some extra food coloring in my closet so I gave my girl a rainblowjob!

Rainboosie 

A gay best friend you think of as a brother or sister. The bond you share is inseparable.
A LGBT boo

"Going out to party with my rainboosies tonight."

Shitting Rainbows 

Someone who has such extraordinary luck that if they were to defecate a beautiful rainbow would come out of their anus rather than faeces.

"Went into town with Jim last night, he ended up shagging a 10/10er and won £100 on a scratchcard"! "Lucky bastard is shitting rainbows".

Pink Fluffy Unicorns Dancing On Rainbows 

The best thing you could imagine because Pink Fluffy Unicorns Dancing On Rainbows are things only seen in dreams and sometimes TV shows and films. They are quick, smart, loyal and fat.

Pink Fluffy Unicorns Dancing On Rainbows is my favourite YouTube song.

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!
