A type of kink involving vomit. Could be inducing barfing or playing with barf.
I have lots of kinks but Rainbow Play isn't one of them

Get the Rainbow Play mug.
A bunch of girls and guys get together. The girls put on different colours of lipstick.

The boy with the most colourful penis at the end of the night wins.
