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.

end of the rainbow 

at the time of climax during sex, the male extracts and deposits on face, back, belly, etc. As the payload lands the male dusts the covered area with glitter(preferably gold) and yells "pot o gold".

The young boy seemed puzzled as his sister ran frantically into the bathroom, and he asked her boyfriend as he came out of her bedroom, " why was she so mad about being all shiny?". The boyfriend replied " she's not mad, she just found the end of the rainbow."
