So how does one taste the rainbow? A whole lot of oral and some strategic timing.


Originating from the ever-horny depths of mid-aughts Urban Dictionary, “rainbow kisses,” a very messy take on 69-ing, is in a social media resurgence, intriguing and seriously grossing out the fine people of TikTok.



A rainbow kiss is when two partners go down on each other while one is on their period. After both parties finish, they reunite right side up for a spectacular make-out session, swapping spit and period blood.

Though it appears very few creators have actually tasted the rainbow — because, gross! — the term alone has morphed into a meme, sparking shitposts, frantic Google searches, and an entire TikTok trend dedicated to capturing couples’ reactions to learning about what the colorful smooch entails.


“Yeah, whoever decided to invent this, is a whole different level of freak,” Twitch streamer Ryen Solos captioned his take on the trend.

Meanwhile, others shared how the reality of the term far exceeded their largely G-rated — and arguably naive — expectations of what “rainbow kisses” would entail.


“I thought it was two people eating rainbow lollipops and then kiss I’m crying,” @_vex_x_x wrote of how they discovered the real meaning of the viral act, another citing a Skittles commercial as how they envisioned the peck to go.

So take it from rainbow kissing’s viral foray: Though we may pretend to be shocked and horrified by all the crazy sex stuff the internet has to offer, our morbid curiosity will always get the best of us.


For as long as humans have sex, and the internet, sex terms like pink canoes and Iglooing, will always go viral.
