The phrase “rainbow kiss” refers to a purported sex act. It is described as involving oral sex performed by a woman on a man, followed by her engaging in menstruation and then performing oral sex on the same man again. The term gained notoriety through its circulation on social media platforms, including TikTok.
The alleged act is not universally practiced and is often considered a myth or urban legend. Information surrounding the concept is frequently exchanged through online forums and social media, resulting in its widespread discussion and, in some instances, misrepresentation. The prevalence of the discussion is more significant than evidence of the act itself.
