You’ve seen it all over Instagram, Facebook, and Snapchat—millennials sticking out their tongues in selfies and group photos like it’s second nature.
At first glance, it seems like a silly, harmless gesture. But if you dig deeper, it reveals layers of generational behavior, digital identity, and emotional self-expression.
So, why do millennials stick their tongue out in photos? Is it just a quirky trend, or does it say something deeper about how this generation sees themselves—and wants to be seen?
Let’s break it down.
Why Do Millennials Stick Their Tongue Out in Photos?
Millennials stick their tongues out in photos as a playful, non-serious gesture to express authenticity, humor, rebellion, and relatability.
Influenced by pop culture, emoji culture, and social norms on social media, the expression reflects a desire to appear unfiltered, fun, and emotionally approachable.
But there’s so much more to the story.
The Psychology Behind the Tongue-Out Expression
It’s Not Just a Pose—It’s a Social Cue
In body language, sticking out your tongue (especially slightly and playfully) communicates:
- Shyness or embarrassment
- Playfulness or teasing
- Rebellion or mock defiance
- “I know I’m being silly, and I’m okay with it.”
According to body language expert Dr. Lillian Glass, this gesture can disarm the viewer by breaking down seriousness:
“It’s a way of saying, ‘I’m not perfect, and I’m not trying to be. I’m human.’ That vulnerability is charming.”
In psychology, this is called “affiliation signaling”—using facial expressions to invite connection.
A Generational Shift from Posed to Candid
Boomers and Gen X grew up with posed portraits. Think studio photos, stiff smiles, and uncomfortable eye contact.
Millennials, on the other hand, came of age during:
- The rise of digital cameras
- The MySpace selfie era
- The Facebook “tag your friends” boom
This gave rise to a new value: “Real is better than perfect.”
Sticking out the tongue became the perfect anti-pose: a symbol of not taking oneself too seriously and intentionally “ruining” the perfect shot. It’s the visual rejection of perfection culture.
Pop Culture Made It Cool
Celebrities and influencers didn’t just influence millennial fashion—they shaped how millennials present themselves online.
Famous tongue-out icons include:
- Miley Cyrus – Her tongue-out poses during the 2013 VMAs sparked a global trend.
- Cara Delevingne – The supermodel often used the tongue-out expression to subvert fashion expectations.
- Kesha, Rihanna, and Katy Perry – Pop queens who blended wildness with humor.
By doing something outrageous and silly, these celebrities permitted millennials to be unserious.
It wasn’t about looking beautiful—it was about being bold and owning your weirdness.
It Mirrors Emoji & Meme Culture
Millennials are the emoji generation. Since the early 2010s, emojis have shaped how they communicate emotion online.
Tongue-out emojis like:
- 😜 (winking tongue)
- 😛 (playful tongue)
- 😝 (wild tongue)
are used to indicate:
- Joking
- Teasing
- Playfulness
- Mild sarcasm
So when millennials take selfies, they often mirror how they feel digitally. It’s part of their visual language—an IRL emoji.
A Nod to Childhood Playfulness
In developmental psychology, sticking out your tongue is one of the earliest forms of nonverbal expression. Babies do it instinctively. Kids use it to tease or laugh.
By carrying that into adulthood, millennials tap into a nostalgic, innocent behavior—a subconscious regression into a time before adult responsibilities.
Especially in high-stress environments or social settings, sticking out the tongue can act as a self-soothing mechanism.
A Defense Against Camera Anxiety
Not everyone likes being photographed. Millennials, despite growing up in the social media era, are still self-critical, especially when it comes to body image.
Instead of smiling stiffly and worrying about how they’ll look, some millennials instinctively do something goofy (like sticking out their tongue) to:
- Control the moment
- Lower expectations
- Redirect judgment with humor
It’s like saying:
“I know I’m being photographed—but I’m not taking it seriously, and neither should you.”
Emotional Mirroring in Group Photos
Tongue-out photos often appear in groups, and that’s no coincidence.
When one person in a group photo makes a silly face, others follow suit. This is a phenomenon called emotional mirroring, where we copy expressions to match group dynamics.
It helps reinforce bonds by signaling:
“We’re in this fun moment together.”
It’s also safer to be silly in a group—you’re less likely to be singled out for looking “weird.”
Visual Disruption in a Perfect Feed
Social media feeds are flooded with polished, filtered images. So what stands out?
A mid-laugh, tongue-out selfie.
A goofy face in a sea of curated poses.
That visual disruption increases engagement by:
- Catching your eye
- Adding humor
- Breaking the fourth wall
The tongue-out pose humanizes the poster. It breaks perfection fatigue and adds a sense of “this is real life, not a magazine.”
Reinforcing Internet Identity
For many millennials, the internet isn’t just a place—it’s a performance space.
Their online identity is a curated version of themselves, and tongue-out photos signal:
- “I’m chill and down-to-earth.”
- “I don’t take myself too seriously.”
- “I have a sense of humor about life.”
It’s branding, but the kind that rejects branding. And in the irony-loving millennial culture, that’s the ultimate flex.
Globalized Expression of Humor
This isn’t just a Western trend. In:
- In Japan, sticking out the tongue (tehepero) is a cute, bashful gesture
- K-pop culture, idols use the expression for fan service and charm
- TikTok trends worldwide have adopted it for dances, pranks, and “chaotic energy” videos
Millennials absorbed this global media landscape, incorporating cross-cultural gestures into their everyday photo behavior.

But Not Everyone Likes It
Interestingly, some Gen Z users now view the tongue-out face as “millennial cringe.” They’ve shifted toward:
- Deadpan stares
- Peace signs
- Ironically awkward smiles
That’s the beauty of generational trends—they evolve, rebel, and refresh every few years. But for millennials, the tongue-out expression is still iconic.
Final Thoughts: Why Millennials Love the Tongue-Out Selfie
Sticking out your tongue in a photo is more than a goofy face. It’s a generational expression of authenticity, rebellion, and playfulness.
Millennials grew up in a time of rapid change—from analog to digital, serious to casual, posed to candid. The tongue-out pose reflects that evolution, offering a moment of vulnerability, humor, and realness in a world of filters and likes.
It’s not just what they do—it’s who they are:
- Unfiltered
- Fun
- And unafraid to be silly
So the next time you see a millennial with their tongue out in a photo, know that behind the goof is a quiet act of emotional self-expression.
