The first time I heard this term and probably the first time anyone ever heard it was on the Oprah show in the summer of 2004. The show was entitled, "Do You Know What Your Teen is Really Doing?" Oprah invited a guest which obviously was hip and hop and all that and could easily infiltrate those naughty secretive teens to see what they were REALLY doing.

Get this, There is a SECRET LANGUAGE of TEENS! No wonder parents can't communicate! So the guest described to the world completely esoteric terms such as "Rainbow party" and "hoovering".

Since then, the term 'rainbow party' has been overly-used, and has even earned an episode of HUFF, in which a teenage boy goes to a 'rainbow party' and his parents later find lipstick on his underwear.
Oprah: Whats a rainbow party? Is that like, some event for PFLAG?
Guest: Oh no no no! Don't let those dirty slutty teens fool you.
Oprah: Oh, I won't!!
Guest: See, a rainbow party is... get this... a party that only about a couple of people actually do in the real world, but we decided to tell everybody cause YOU COULD BE NEXT!
Oprah: Gasp!

A party where maultiple girls each put on a different shade of lipstick, and suck off a guy. Hence, the guy will have a "rainbow" colored dick.
"Yo Sarah, what color are you wearing to the rainbow party?"
"What's a rainbow party?"
Well, Chrissy, if Sarah wore red lipstick, and I wore purple, your dick would be purple and red."
"Oh. Oh God."

A Rainbow party is when a bunch a girls get together and suck a guys dick with the different coloured lipstick. It leaves the guys dick with a rainbow effect. This is good if a guy wants to wank without porno magazines or movies. Who ever sucks the furthest wins
We had fun at the rainbow party...I sucked with red and Mandy sucked with Pink...he had the two colours of the rainbow and he was already cuming hard...
OPRAH DID NOT INVENT RAINBOW PARTIES...THEY WERE AROUND IN THE 70'S

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.
