Rainbow Party 

A "rainbow party" is supposed to be a party where girls wear different shades of lipstick and suck a guy off. In actuality, it is a term invented by Oprah and no teen had heard of it until her show in 2004.

Oprah invented rainbow parties so parents can lock up their teens and send them to boarding school.

rainbow party 

In the US, it is apparently a euphemism (or media-invented myth)for rather lewd naughtiness (see all other definitions). In the UK, it means jelly, ice-cream and dressing-up as Zippy, Bungle, Geoffrey, George, Rod, Jane or Freddy and singing "The Wheels on the Bus". The latter seems condusive to a much more satisfying experience.

Yank: Dude, I'm so emotionally crippled and shallow, I went to this badass Rainbow Party last night. Now I feel even more empty and my dick's kinda itchy.
Limey: I say, old bean, I had a Rainbow Party last week! We all had a beezer time, despite Bungle having eaten too much jelly and ice-cream.

Rainbow Farts 

To be so excited about something you almost shoot the gayest thing in the world out of your butt. Similar to pooping kittens.

I saw the cutest little puppy earlier and it made me shoot off several rainbow farts.

rainbow stalin 

Rainbow Stalin is a false interpretation of the lyrics in the song "Rainbow Stylin'" by Swedish electronic group "The Similou". This interpretation became a hit on YTMND featuring Soviet dictator Stalin or some form of meat loaf and rainbow lights.

"And all this love (loaf) saved up for nothing, I never felt so blue, and all this love (loaf), Rainbow stylin' (Stalin)"

rainbow stylin' = rainbow stalin

A flaming homosexual who is constantly screeming about intolerance toward homosexuals while at the same time is intolerant toward anything or anyone non-homosexual

That tired old queen is such a Rainbow Nazi.
