The act of sticking you whole hand up someones asshole, then pulling it out and smearing it on them, openhanded, in a semi-circle pattern to resemble a rainbow. Similar to a dirty sanchez, but this is much bigger and can be done on other parts of the body.

Also, when a guy goes down on a girl while she is on her period, and Gets all the blood in his mouth. And a girl has blood/cum in their mouth, they kiss each other.
