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.
Oprah invented rainbow parties so parents can lock up their teens and send them to boarding school.

I've been to two rainbow parties now. I didn't last long at the first one seeing all of those girls giving head at the same time with the different lipstick. Julie had me first with yellow lipstick, and I blew my load in her mouth within a minute or two. When my penis was less sensitive a little later, Karen gave me another one with her bright blue lipstick. Since I didn't cum, Pamela took over with her green lipstick when the bell was rung. She asked me to cum on her chest if I needed to, and after I did, I was done for the night.

At the second party, I was more relaxed, and before the end of the night had let each girl leave her mark.
