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.

4. Silly Billy called all his friends to come to the Rainbow Party
A party where girls each where a distinctly different color of lipstick, and at the end, boys compare with each other how many marks they have in a judge of coolness.
Even kids in junior high have rainbow parties.
To recieve fellatio from many different girls with different colored lipsticks so your "unit" appears to be rainbow colored
" I had fun at the rainbow party."
A sexual party with two or more women and one or more men. The females perform oral sex on the male(s). The colors of the lipsticks are left on the male's penis after oral sex--making the penis resemble a rainbow when many women have perormed oral sex on him.
"Lisa was the best at the rainbow party--crimson always beats red and blue!"
A bunch of girls come to a 'Rainbow Party' and so do a bunch of guyz. The girls each put on a different shade of lipstick from the rainbow, and then they all get in a circle, guy girl guy girl, each girl sucking a guyz dick, leaving a colored print on the guys dick, eventualy each girl gets each guy and each guy's dick is like a rainbow.
You get dah point.
When a crowd of girls give one or more guys a blowjob
wearing different color lipsticks. This causes the penis to have different shades on it, therefore making it look like a rainbow.
Note: Has nothing in particular to do with homosexual orientation (though it could)
Taylor wore red lipstick, Vicky wore orange, Sarah wore yellow, and Caroline wore green. They sucked intensely at the rainbow party, almost like a hoover. That was all I saw because the dick had cummed with those colors on it. I bet the other girls felt left out...
