A word that was made up by Oprah in order to lure parents to be overly cautious for absolutely no reason.
Oprah: "Your daughter is a slut, she goes to rainbow parties, so lock her in a stone cell for the rest of her life, because I'm Oprah and I know everything!"

Supposedly a party where girls wearing different colored lipstick all have oral sex with one or more guys, leaving the guys with a "rainbow" colored penis. Some people appear to believe that it's just an urban legend.
"I felt left out because I only had six different colors of lipstick on my dick when I left the 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.

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.

When a young group of teenagers goes to a party and each girl wears a different colored lipstick. Then all the boys line up and each girl proceeds to "go down" on the boys. The girl with her lipstick farthest down on the most boys is deemed "winner"
"'Mom! My throat is too sore from last night's rainbow party!' 'It's ok, sweety, you can stay home from school today'"
