This is where I had painful results. I had a serious reaction to something in the lipstick (the next morning). It caused my penis to swell 2 times its normal erect width (but it wasn't erect). It was also red, inflammed, and itched badly. To get relief, I had to get a shot in my penis (OUCH!) and put a creme on it. It took about a week before it was back to normal. My advice - avoid these partys!
The results from the rainbow party left me with serious pain!

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.

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.

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.

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...
