Why Do People Chew with Their Mouths Open?

by | Feb 5, 2025

For the love of all that is decent and remotely civilized, why in the name of everything sacred do people insist on chewing with their mouths open? Are you trying to ruin humanity one bite at a time? Is the goal to show us all what your digestive system looks like in real time? Because CONGRATULATIONS, mission accomplished. Nothing screams “I have zero regard for anyone around me” like opening that food dumpster you call a mouth and letting the world witness the absolute horror show going on inside.

You know what I don’t need in my life? The sound of your mouth slapping together like two soggy flip-flops as you grind through your lunch like a cow chewing cud. No, really, thanks but no thanks. The visual of your half-chewed burger swirling around your tongue like it’s doing laps is bad enough. Do we all need to hear it too? Is this some new form of torture? It’s like the Geneva Convention outlawed waterboarding, so you decided to show up and terrorize my soul with your inability to shut your damn mouth while eating.

Now, let’s get into why these mouth-breathers can’t manage to chew like functional humans:

1. Complete and Utter Laziness

Honestly, is it that hard to close your mouth? Does your jaw have some sort of medical condition that prevents it from functioning like a normal human’s? Are your lips too tired from all that important talking you do about absolutely nothing? Chewing with your mouth closed requires the bare minimum effort—bare minimum. But here you are, acting like the simple act of closing your trap is equivalent to running a marathon.

2. They Just Don’t Care

Yep. That’s it. These people are the human equivalent of that guy who drives 10 miles under the speed limit in the left lane—just out here making life miserable for the rest of us because they can. These are the kind of people who’d probably sneeze directly into your face and then act like you’re the one with the problem. No basic courtesy, no regard for the fact that everyone around them wants to die a little more every time they take a bite. They know exactly what they’re doing, and they just don’t care. Sociopathic tendencies, but make it dinner.

3. Blissful Ignorance

Some people are just so profoundly unaware of themselves that they probably don’t even know what century we’re living in, much less that their open-mouth chewing is making us all die inside. They’re the same people who will talk over you in a conversation and then wonder why no one invites them anywhere. Self-awareness? Never heard of it. Mouth open, food flying, noises that should be illegal in polite society—that’s their whole vibe.

4. Raised by Wolves?

Look, maybe no one ever taught them. Maybe they were raised in the wilderness by a pack of wild animals that have better manners than they do. Or maybe their parents were just as hopeless, and now we’ve got this generational chain of mouth-open-chewing barbarians roaming the earth like it’s the Stone Age. Honestly, that’s the only explanation that makes any sense. At some point in their evolutionary chain, someone gave up, and now we all get to suffer because they never learned how to use a fork like a normal human.

5. Desperate for Attention

Maybe, just maybe, these people actually like the disgust they generate. They’ve figured out that their only way to be noticed is by chewing like a Neanderthal in front of an audience, so here they are, broadcasting their saliva orchestra for all to enjoy. Congratulations, you’ve won. You’ve got our attention, and we all now hate you. Mission accomplished.

So there you have it. People chew with their mouths open because they’re lazy, inconsiderate, blissfully ignorant, possibly feral, or desperately trying to become the most repulsive thing in your day. And honestly? They’re succeeding.
