Rainbow

When a guy goes down on a girl on her period and keeps it in his mouth, then she goes down on him and keeps it in her mouth, then they kiss and mix it together (a.k.a. period blood and jism)

She's on the rag, so last night they made a rainbow.

Rainbow shower

Where the recipient of a rainbow shower is urinated on by multiple people simultaneously by people with varying levels of dehydration.

For extra points, urinators may have consumed beetroot (makes urine pinky-red) or berocca (green colour) in advance.
