Alright, let’s discuss a trend that has completely shocked the internet — the rainbow kiss. Before you search for it (and wish you hadn’t), let’s explain it in the most kid-friendly way we can.
If you’re someone who has already searched for it and are now holding onto your sanity, don’t worry, you’re not the only one. Many people are actually saying they feel “scarred for life” after discovering this term.
A trend that’s… Not for the faint of heart
The rainbow kiss might sound like a fun and creative art project, but it’s actually not. Here’s a heads up: it includes bodily fluids — specifically period blood and semen — and it’s typically done in the classic 69 position.
Now, here’s the surprising part: after a certain moment, one person with semen in their mouth and the other with menstrual blood share a kiss. What do you get? A colorful mix that some might call… a ”rainbow.”
To say it simply, it’s not what most people think of when they hear the word “rainbow.”
Internet reacts: “I should never have searched that…”
People who were unlucky enough to search for this thing on Google were really shocked. One TikToker said, “I am shaking.” Another person added, “I should never have searched that…” We understand. You can’t unsee it, everyone.
One very brave person promised, “I’m never going to do that.”
And we totally get why.
Someone else described it perfectly by saying: “Scarred for life.”
If you haven’t searched for it yet, consider this your warning. Be careful.

What’s the Deal with “Snowballing,” Though?
The rainbow kiss is often mistaken for something else known as “snowballing,” which involves some, let’s say, creative exchanges with semen. It’s a completely different trend that honestly takes a different kind of courage to look into.
According to Dr. Wendasha Jenkins Hall, a sex educator from Atlanta, the rainbow kiss is basically a “level up” from the standard 69 position. So if you thought the regular 69 was already pushing limits, just wait until you learn about the rainbow kiss.
“Rainbow kisses are not for the faint of heart,” Dr. Hall explains. “This is a next-level sexual act.”
Some people believe that too much shame is attached to periods and period sex — and that really shouldn’t be the case,” says Neil Cannon, PhD, a certified sex therapist and supervisor from Denver.
“When it comes to sex, all paths lead to shame,” he notes. “Regarding the shame linked to menstruation, think of blood as just another bodily fluid, and it’s nothing more than what we choose to make of it.”
Is it safe? Spoiler: Not really
So, here’s the big question: Is this safe?
The answer is kind of a no. If you’re thinking about giving this a try, make sure you and your partner are both old enough, completely agree, and definitely free of STIs.
Semen and menstrual blood can carry STIs like HIV, syphilis, and hepatitis. If you or your partner have any cuts, sores, or bleeding gums (yikes), the chance of getting an infection goes way up.
Dr. Heather Irobunda, MD, says that if you’re not sure about your partner’s STD status, this is one trend you should probably avoid.

Actually, whether you’re single or in a relationship, Dr. Irobunda recommends that you get tested regularly — a good guideline is every three to six months.
Rainbow kisses have been around for some time, but they really show how crazy sex slang can suddenly take off online.
They also highlight how much our conversations about sex, bodies, and kinks have changed — things that used to be talked about quietly are now openly discussed, trending on TikTok and other social media platforms.
So, there you go. The rainbow kiss: the popular act that nobody really asked for, but here we are. If you’re thinking about trying it, just make sure you understand what it involves (and maybe avoid Googling it unless you’re prepared for some really wild responses).
