Practice whereby lipstick of different colour is applied on lips of a few people after which they rim the member of a male person making it looks like a rainbow after everyone is done!
The high school girls in larger towns will party at a friends house and agree to "Rainbow Rimming" a guy that they invited for that purpose. Its not attached to any sexual activity at the time its performed. Each girl should just go as far as she can and apply the lipstick to the member using her lips only!
