You’ve seen it. That yellow face, jaw practically hitting the floor, eyes wide and unblinking. It’s the mouth wide open emoji, or as the Unicode Consortium officially calls it, the Face with Open Mouth. It looks shocked. Or maybe it’s just breathing? Honestly, depending on who you’re texting, that little icon could mean "I'm terrified" or "I just saw a cat wearing a tiny hat." It’s one of those weirdly versatile symbols that somehow manages to be both incredibly specific and frustratingly vague at the same time.
The thing about the mouth wide open emoji is that it sits in a crowded neighborhood. You’ve got the Astonished Face (the one with the "X" or "crossed" eyes sometimes, or just very rounded ones), the Hushed Face, and the Screaming in Fear emoji. It’s a lot. But this specific one—the one with the flat, un-arched eyebrows and the big, dark void of a mouth—has its own special vibe.
The Technical Reality of the Mouth Wide Open Emoji
Let’s get the dry stuff out of the way first. This emoji was approved as part of Unicode 6.1 back in 2012. It’s been around for over a decade. In the world of tech, that’s basically ancient history. When it first landed on iOS and Android, it looked a bit different than it does now. On older Samsung devices, for instance, it used to look genuinely horrified, whereas the current Apple version looks more like a mild "Oh!" or a gasp.
Jeremy Burge, the founder of Emojipedia, has often pointed out how these cross-platform differences cause massive communication breakdowns. If you send the mouth wide open emoji from a Google Pixel to an iPhone, you might think you’re expressing a neutral "wow," but the recipient might see something that looks a bit more like a jump-scare reaction.
It’s just a circle. A yellow circle with three holes. But those three holes do a lot of heavy lifting in our daily digital lives.
Surprise vs. Shock: Where Do We Draw the Line?
People get confused. Is it surprise? Is it shock? Is it just someone being a "mouth breather"?
Context is king here. If your friend texts you that they just won the lottery, you drop the mouth wide open emoji because you’re stunned. It’s a positive shock. But if they tell you they just dropped their phone in the toilet for the third time this week, that same emoji suddenly transforms into a "dude, again?" kind of disbelief.
The nuance matters. According to some linguistic studies on digital communication, the lack of "scrunching" in the eyes of this specific emoji makes it feel less intense than its cousins. It’s a "soft" shock. It’s the face you make when you realize you forgot to take the chicken out of the freezer, not necessarily the face you make when you see a ghost.
The Gen Z Pivot and Why It’s Not Just for "Wow" Anymore
If you’re over 30, you probably use this emoji for its literal meaning. Someone says something surprising, you use the surprise face. Simple. Done.
But talk to a teenager. Or look at TikTok comments. The mouth wide open emoji is often used ironically or as a placeholder for a specific type of "deadpan" humor. Sometimes it’s used to mimic a "stunned silence" that isn't actually about being surprised, but rather about how stupid or weird a situation is. It’s the digital version of staring at someone blankly while your mouth hangs open because you don’t even know where to start.
It’s also heavily used in the gaming community. You’ll see it in Twitch chats during a "pro gamer move" or a massive fail. In that world, it’s almost like a "poggers" Lite. It signals that something significant happened, and the chat is collectively gasping.

Why Some People Hate This Emoji
There is a subset of the population that finds the Face with Open Mouth... unsettling. It’s the eyes. They don't move. They don't have pupils. It’s just two black dots staring into your soul while the mouth remains a bottomless abyss.
In some UI/UX circles, this is referred to as a "flat" expression. Because there are no slanted eyebrows to indicate fear or curved lines to indicate joy, the emoji is a blank slate. This can lead to "emotional masking." You use it when you don't actually know how to feel. It’s the "I have no words" button.
Comparisons: Not All Open Mouths Are Created Equal
Let's look at the lineup. You need to know which one to pick so you don't look like a total amateur in the group chat.
- The "Hushed" Face: Small mouth, looks like it’s saying "oops." Use this when you've shared a secret you shouldn't have.
- The "Astonished" Face: Small pupils, often has those little "shock lines" around it on some platforms. This is for when you’re actually rattled.
- The "Mouth Wide Open" (Our Hero): Perfectly round mouth, neutral eyes. This is the Swiss Army Knife of reactions.
- The "Fearful" Face: Blue forehead. Stay away from this unless you're actually scared or have a 102-degree fever.
Using It for Brand Voice and Marketing
Believe it or not, brands spend millions of dollars figuring out which emojis make people click "Buy Now." The mouth wide open emoji is a favorite for "Flash Sale" announcements. Why? Because it triggers a psychological "stop" response.
When we see a face with an open mouth, our brains are hardwired to look for the source of the stimulus. Evolutionarily speaking, if a tribe member had their mouth open, it usually meant they'd spotted a predator or a fruit tree. Today, it just means there’s 20% off espresso machines. But the primal lizard-brain reaction remains. It grabs attention in a way that a smiley face just doesn't.
The Cultural Divide: It’s Not Universal
In some Eastern cultures, particularly in Japan where Emojis originated (the word comes from 'e' for picture and 'moji' for character), the emphasis on emotion is often in the eyes rather than the mouth. This is why many Japanese emoticons (kaomoji) like (^_^) focus on eye shape.

The mouth wide open emoji is a very "Western" style of expressing emotion—loud, visible, and exaggerated. In some contexts, using it can come across as a bit "too much" or overly dramatic. It’s the digital equivalent of shouting "WHAT?!" in a quiet library.
A Note on Accessibility
For people using screen readers, this emoji is usually read aloud as "Face with open mouth." That’s pretty accurate. However, it doesn't convey the intent. If you use five of them in a row to show you're laughing (which some people do for some reason?), a screen reader user just hears "Face with open mouth, Face with open mouth, Face with open mouth..." It’s worth keeping in mind that while emojis add flavor, they can sometimes muddy the waters for accessibility.
How to Level Up Your Emoji Game
If you want to use the mouth wide open emoji like a pro, stop using it by itself. Pair it.
- Pair it with the Exploding Head emoji if your mind is truly blown.
- Pair it with the Sparkles if you’re surprised by something beautiful.
- Pair it with the Clown face if you’re shocked by someone’s sheer audacity.
It’s a modifier. It sets the volume of the sentence. Think of it as a physical gesture. You wouldn't just stand there with your mouth open for ten minutes in real life (hopefully), so don't let it be the only thing you send in a text.
Practical Steps for Better Digital Communication
Next time you reach for that gaping yellow maw, take a split second to think about what you’re actually trying to say. Are you actually surprised? Or are you just trying to acknowledge a message without typing words?
If you’re in a professional setting, maybe lean toward the Hushed Face or just, you know, use actual adjectives. But in the group chat? Let that jaw drop. It’s the quickest way to say "I saw that, and I am reacting" without having to put in the effort of a "LOL" or a "Wow."
Check your phone's specific rendering of the emoji too. Open your "Sent" messages and see how it looks compared to the ones you receive. You might find that you've been sending a "horrified" face when you meant to send a "mildly interested" one all along. Knowledge is power. Or at least, it prevents awkward misunderstandings with your boss.
