Expanding Brain

The Expanding Brain meme — that iconic multi-panel image of progressively glowing brains — was born on January 31st, 2017 on Reddit's r/dankmemes, when a user named janskishimanski paired increasingly absurd spellings of "who" with increasingly cosmic-looking brains. The original post earned nearly 1,200 upvotes and set off a meme format that's still going strong almost a decade later.

What Is the Expanding Brain Meme?

At its core, the Expanding Brain meme (also called Galaxy Brain) is a multi-panel exploitable image. Each row shows a brain that is progressively larger and more luminous — from a tiny, dull smooth brain to a massive, galaxy-filled cosmic brain radiating transcendent energy. Each panel is paired with a label, an idea, or an option.

The punchline is almost always ironic. The most ridiculous, absurd, or counterintuitive option gets the biggest, most glowing brain. "Using a fork correctly" gets the small brain. "Eating spaghetti with your hands to avoid washing dishes" gets the galaxy brain. The format flips conventional wisdom on its head — the dumber or more chaotic the idea, the more intellectually enlightened it supposedly is.

That inversion is what makes it infinitely reusable. You can drop any topic into the format — programming languages, parenting choices, fast food orders, geopolitical strategy — and the structure does the comedic heavy lifting.

The Origin: Whomst on r/dankmemes

The template itself has roots in earlier "brain size" images that circulated on image boards, but the viral moment that launched the meme as we know it came from the Whomst meme. "Whomst" was a parody of English grammar pedantry — a series of increasingly ridiculous variants of "who": who → whom → whomst → whomst'd → whomst'd've.

On January 31st, 2017, Redditor janskishimanski fused the Whomst meme with the brain-size image format, posting a 4-panel meme to r/dankmemes. The smallest brain used "who." The next step up used "whom." Then "whomst." The final, galaxy brain tier used "whomst'd've" — the most absurd grammatical monstrosity — paired with the most luminous, cosmos-filled brain imaginable. The post collected nearly 1,200 upvotes.

It was a perfect marriage: the self-important grammar-correcting energy of "whom" culture, skewered by taking it to such an extreme it imploded into comedy. Reddit got the joke immediately.

How It Spread: February 2017 and Beyond

After that first viral hit, Expanding Brain variations exploded across r/dankmemes and r/MemeEconomy throughout February 2017. The template was applied to video games, political choices, food preferences, and pop culture. Each new subject spawned dozens of variations as Redditors competed to create the most absurd final panel.

A video compilation posted by user BagelBoy in February 2017 became its own viral hit, racking up over 2.1 million views. The format was no longer just a static image — it was a whole genre.

By mid-2017, mainstream media had picked up on it. PopSugar, New York Magazine, and Mic all covered the Expanding Brain phenomenon. The meme crossed over from Reddit into Twitter, Instagram, Tumblr, and Facebook, where it found massive new audiences who may never have visited r/dankmemes in their lives.

Why Does the Expanding Brain Meme Work?

The Expanding Brain format has an almost magical staying power. Unlike many memes that burn out after a few weeks, it keeps getting rediscovered and remixed years later. Here's why it works so well:

1. Hierarchy Humor Is Universally Legible

Humans understand rankings instantly. Bigger = better. More glowing = smarter. The visual hierarchy of the meme communicates the joke structure before you even read the labels. The format is self-explanatory to someone who has never seen it before, which is rare for meme formats.

2. It's a Vehicle for Intellectual One-Upmanship (Ironically)

The Expanding Brain meme is ostensibly about intelligence — bigger brain = smarter idea. But the ironic inversion means it's actually used to mock intellectual pretension. It's the internet's way of calling out "galaxy-brained" reasoning: the kind of elaborate, convoluted logic that somehow arrives at a completely unhinged conclusion. Seeing that "galaxy brain" label applied to "just eat the pizza directly from the delivery box to avoid washing plates" is funnier because it borrows the aesthetic of profound insight.

3. It's Infinitely Extensible

You can apply the format to literally anything that has multiple options with a perceived quality scale. Sports strategies. Cooking shortcuts. Software architecture. Dating advice. Tax law. The template doesn't care what goes in it — it just needs a topic with at least three tiers. This universality is why the meme never truly dies; it just migrates to the next hot topic.

4. The Visual Escalation Rewards Patience

Unlike a single-image meme, the Expanding Brain rewards reading all the way to the end. The joke lives in the final panel — the cosmic galaxy brain that reveals what the "most enlightened" choice actually is. That slow buildup to the punchline creates genuine comedic timing in a static format, which is technically impressive.

Galaxy Brain: The Meme That Became a Concept

The term "galaxy brain" has transcended its meme origins to become a legitimate piece of internet vocabulary. On Reddit and Twitter, accusing someone of "galaxy-brained logic" means they've reasoned their way into an absurd position through a chain of steps that each seem plausible. It's a rhetorical concept now.

The Know Your Meme page for the format actually redirects from "Expanding Brain" to "Galaxy Brain" — an acknowledgment that the galaxy brain tier became the defining element that stuck in cultural memory, even more than the full meme format.

Variations and Spinoffs

The Expanding Brain template has spawned many variations. The Vince McMahon Reaction format — showing WWE legend Vince McMahon with progressively more shocked expressions — followed the same escalating hierarchy structure. The Motion Blurred Astronaut images (from a photography textbook demonstrating shutter speed effects) went viral in April 2017 partly because they looked like a natural Expanding Brain spinoff.

In 2018, a series featuring Drake's Sprite commercial explosion adapted the three stages of Drake blowing up into an Expanding Brain format. An Instagram post by @SonnySideUp in June 2018 using a "Thanking the Bus Driver" theme with the format got 43,600 likes in its first 90 days.

Each era finds something new to pour into the template. The format is essentially a blank canvas that takes on whatever cultural conversation is happening at the moment.

Put Your Face in the Expanding Brain Meme

The Expanding Brain meme is one of the most satisfying face-swap targets on the internet. The four-panel format gives you four different expressions to play with — from confused or unimpressed in the small-brain panels, to absolutely transcendent and glowing in the galaxy brain tier.

Imagine your own face in that final cosmic panel — eyes wide, brain glowing with the light of a thousand galaxies, because you just decided to eat cereal with orange juice instead of milk. That's peak Expanding Brain energy.
