A gathering where many girls wear different colors of lipstick. Each girl proceeds to give a blowjob to the boy or boys that are attending the "party." The color of lipstick that the girl giving head was wearing then rubs off onto the boys dick. After every girl at the party gives the boy head and all of their lipstick rubs off onto his dick, the penis ends up with what appears to look like a rainbow of colors on it. (The girls at this party are usually classified as sluts/skanks/whores)
guy 1: "Dude. This rainbow party is bitchin'!"

guy 2: "Hey man, do you know where the girl wiht the red lipstick is? she'll complete my rainbow"

guy 1: "Yea that smut is over there blowing some other guy."

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...

A Rainbow Party is, in all actuality, so that guys can brag to each other how popular they are. The girls wear a different colored lipstick each, suck off the guys they think are hot, until all of the do-able guys have been revealed. Then the guys count how many colors they have, and compare.

Ladies and gentleman of Urban Dictionary, it IS real! I had a good amount of girls in my class, year 2000, come up to ask if I wanted to join. There were pictures all over the school, not in the eyes of teachers, that I got to view and I was quite ashamed! Never even heard of Oprah talking about it, and neither had any of these girls. I assure you, Oprah did not make it up!
John could not believe how many colors he had on his penis! He thought surely he'd only get three at the very least. The sudden boost of confidence he felt was well worth the unease he had had before he joined in on the rainbow party.
