Rule 34: If It Exists, There’s Porn of It (And Yes, Even That Thing You’re Thinking Of)

Welcome to the internet, traveler. Perhaps you were looking for wholesome dog memes, a banana bread recipe, or that one obscure Vine from 2014. But instead, you’ve stumbled into the weird, wild, and worryingly well-drawn world of Rule 34—the internet’s most notorious “rule” that has turned the web into both a creative playground and a fever dream from which there is no escape.

Let’s buckle up and take a deep dive—safe for work, we promise—into this curious rule that has baffled boomers, entertained millennials, and corrupted Gen Z (and possibly Gen Alpha before they hit middle school). Whether you’re a curious bystander or a seasoned meme archaeologist, it’s time to talk about that rule.

What Is Rule 34?

Rule 34: “If it exists, there is porn of it. No exceptions.”

Yes. That’s it. That’s the rule. No fine print, no loopholes, no “terms and conditions apply.” If it’s a thing—even a conceptual thing—someone, somewhere, has decided it needs to be sexualized. Whether it’s a kitchen appliance, a cartoon sponge, or the concept of time, Rule 34 artists have said, “Hold my stylus.”

Where Did It Come From?

Like many things that feel like they’ve always existed (like glitter or existential dread), Rule 34 emerged from the chaotic primordial soup known as early 2000s internet culture. Specifically, it was first documented on a list of “Rules of the Internet” posted on a site called 4chan, where digital mischief, memes, and questionable decision-making roamed freely.

Though no one knows who exactly coined it (possibly a bored 17-year-old with too much Photoshop access), Rule 34 was posted in 2004 and quickly cemented itself in the web’s cultural DNA. The original post read simply:

“Rule 34: If it exists, there is porn of it. No exceptions.”

Some legends say there was a Rule 35 that followed (“If there is no porn of it, it will be made”), which really drives home the “prophecy” vibe.

Why Does It Exist?

Honestly? Because humans are weird.

We anthropomorphize everything. We make sexy versions of Halloween costumes (nurse, firefighter… corn cob?). And the internet gave everyone a place to share their very specific interests, often anonymously, without fear of judgment (or at least with judgment filtered through ironic memes).

Rule 34 is the natural outcome of:

• Creative freedom,

• Sexual curiosity,

• The uncanny ability of the human brain to say, “What if Optimus Prime… but thicc?”

A (Mildly Horrified) Tour of Rule 34 in Action

Let’s take a scroll—er, stroll—through a few perfectly real examples of Rule 34 doing its unholy magic:

• Thomas the Tank Engine? Too many versions. Too much steam.

• The M&M’s mascots? Let’s just say the green one started something no one could stop.

• Shrek? Oh sweet swampy heavens, yes. And way too much.

• The COVID-19 virus? Sadly… yes. With abs. And sultry eyes.

In a world governed by Rule 34, nothing is safe. Your childhood cartoons? Doomed. Your favorite mobile app icons? Someone’s drawn them kissing. That IKEA lamp you felt bad for in the ad? Oh no.

Rule 34 in Gaming

If Rule 34 dictates that “if it exists, there’s porn of it,” then adult game mods are the interactive embodiment of that rule. In the gaming world, fans don’t just draw explicit versions of their favorite characters—they code them into existence. These mods transform popular games into NSFW sandboxes, allowing players to explore fantasies directly through gameplay. It’s Rule 34 with a mouse and keyboard.

Take 심즈 4, for instance: a game about suburban domestic life becomes an adult playground with the WickedWhims mod, adding uncensored intimacy, custom animations, and entire social systems for flirtation and sex. In open-world RPGs like 스카이림 그리고 Fallout 4, adult modding communities such as LoversLab have created vast libraries of erotic content—NPC romance paths, adult-themed magic, and even alternate storylines—all aligning with Rule 34’s philosophy of “no exceptions.” And of course, the notorious “Hot Coffee” mod 에 대한 GTA: 샌 안드레아스 was perhaps the earliest mainstream scandal to show what happens when Rule 34 collides with modding—forcing a ratings reclassification and congressional hearings.

Unlike passive Rule 34 fan art, adult mods are fully immersive, letting users not just see but play out fantasies that game studios would never officially publish. Whether you see it as a creative extension of fandom or a trip into the digital gutter, one thing’s certain: Rule 34 isn’t just drawing anymore. It’s scripting, animating, voice-acting, and modding its way into your hard drive.

The Rule 34 Artist: Modern Day Digital Da Vinci

While you’re out here barely drawing stick figures, Rule 34 artists are rendering 4K ultra-HD anime-style fan art of Mario and Bowser locked in an emotionally intense embrace. Say what you will, but the technical skill involved is often jaw-droppingly good. Some pieces could hang in a museum, assuming that museum is 18+ and has a no-judgment policy at the door.

These artists are:

• Unapologetically creative

• Deeply knowledgeable about obscure fandoms

• Probably using 5 layers of Photoshop and 3 terabytes of reference material

Their work might not be everyone’s cup of tea… but dang it, they’re dedicated.

The Psychology Behind “Why Tho?”

Let’s put on our Freud goggles (yes, they’re shaped like little cigars) and ask: Why is Rule 34 so popular?

• Taboo titillation – The forbidden is fun. Just ask anyone who’s ever eaten cake at 3am or googled “Garfield but sexy.”

• Power over media – Fan art is a way to take control of characters. Rule 34 just… takes it very far.

• Shock value – Some people love the “LOL wut” reaction of making or finding absurd sexual content. It’s like meme roulette.

• Identity exploration – Jokes aside, Rule 34 can offer people a space to explore interests, fetishes, and identities in ways traditional media never touches (pun not intended, but we’re leaving it in).

When Rule 34 Meets Mainstream Culture

You’d think most companies would run screaming from this, but some embrace it—or at least play along.

• Deadpool made jokes about fan shipping and Rule Thirty-Four in the actual movie.

• Blizzard (Overwatch) was surprised (read: mortified) to find their game’s characters were… popular online. Very popular.

• Sonic the Hedgehog’s entire internet existence is one long Rule Thirty-Four cautionary tale, yet the brand thrives.

And let’s not forget Tumblr circa 2011–2018, when entire fandoms rose and fell based on which two characters people were “shipping” (Supernatural fans, we’re looking at you).

When Rule 34 Goes Too Far (Yes, There Is a Line)

While Rule 34 can be fun, absurd, or oddly beautiful, it also raises real concerns:

• Consent – When artists depict real people (celebrities, streamers, politicians), ethical alarms go off.

• Minors – This is serious: Rule 34 of underage characters (even animated) is not okay and often illegal.

• Copyright infringement – Many companies don’t love their IP being used in this way. Legal battles have occurred.

• Harassment – Sometimes, fan communities weaponize Rule 34 to mock or harass people. That’s where creativity ends and cruelty begins.

So while we laugh, it’s also worth remembering that “just because you can doesn’t mean you should” is also a good rule to follow online.

The Rule 34 Counter Movement: “Please Don’t.”

Not everyone’s thrilled to see their favorite characters tangled up in compromising positions. In fact, there’s a growing segment of fandoms and creators who actively request that fans not make Rule Thirty-Four content of their work.

Some even create counter-rules:

• Rule 63 – Gender-swapping characters

• Rule 85 – “If it exists, there’s a plushie of it.” (Now that’s wholesome.)

There are even sites and wikis dedicated to tagging 그리고 filtering out Rule 34 content. Because even internet adventurers need a break.

How to Survive (and Maybe Enjoy) Rule 34

If you’re new to this world, here are some tips for navigating Rule Thirty-Four without losing your sanity or lunch:

1. Don’t search “X + Rule 34” unless you really mean it.

2. Know your boundaries – The internet will show you things you didn’t ask for. Set your filters and avoid the darker corners.

3. Appreciate the creativity – You don’t have to like it, but you can still admire the skill.

4. Don’t shame others – Unless it’s illegal or non-consensual, let people enjoy what they enjoy. The internet’s weird. So are we.

Conclusion: Rule 34—A Mirror, a Meme, and a Monster

Rule Thirty-Four is hilarious, horrifying, endlessly creative, and deeply human. It’s the internet’s version of a carnival mirror: it reflects our obsessions, our humor, our kinkiness, and our unfiltered imagination.

You might not want to live in a world where someone’s drawn intimate fan art of the Duolingo owl, but you do live in it. And that’s what makes the internet a place of strange, magical, and occasionally terrifying beauty.

So next time you’re browsing peacefully and stumble upon something deeply cursed, just whisper to yourself:

“Rule 34. No exceptions.”

Then close the tab, and go pet a dog or something.
