A mix between a rainbow kiss and a dirty sanchez. The guy has sex with the woman while she is on her period, then has anal with her as well. He then takes his cock and rubs it on the womans upper lip, giving her a bloody, fecal moustache.
Guy 1: Did you hear what happened to susie last night?
Guy 2: No, what?
Guy 1: Well she's got the painters in and she got it in both holes from gary, then he rubbed his dick all over her top lip.
Guy 2: Dude, she got the infamous rainbow sanchez!
