The Expanding Brain Meme, Explained

expanding-brain-meme

The expanding brain meme is a multi-panel format that ranks ideas, choices, or takes from “normal” to “transcendent.” Each panel shows a progressively larger, more illuminated brain – starting with a smooth, basic brain and ending with a cosmic, galaxy-sized superbrain radiating pure enlightenment. The joke? The “smartest” option at the bottom is almost always the dumbest, most absurd, or most chaotic choice.

How the expanding brain meme works

The format is simple but endlessly flexible. Four (or more) panels, each with:

  • Panel 1 – Small brain: The normal, sensible option. What most people would do.
  • Panel 2 – Medium brain: A slightly smarter or more creative take.
  • Panel 3 – Glowing brain: Now we are getting somewhere unusual.
  • Panel 4 – Galaxy brain: The most absurd, overthought, or ironically “genius” option.

The humor comes from the escalation. The “biggest brain” move is rarely actually smart – it is usually the most ridiculous, impractical, or unhinged option presented as if it were peak intelligence.

Classic example

Walking to work (small brain) > Driving to work (medium brain) > Working from home (glowing brain) > Not having a job (galaxy brain)

Food edition

Cooking dinner (small brain) > Ordering delivery (medium brain) > Eating cereal for dinner (glowing brain) > Sleeping through dinner entirely (galaxy brain)

Where the expanding brain meme came from

The meme originated on Reddit and Tumblr around 2017, using stock images of brain scans with increasing levels of activity and illumination. The original images showed MRI-style brain scans progressing from a normal brain to one exploding with cosmic energy.

It spread fast because the template is dead simple to customize. Anyone can slot in their own ideas, and the format works for literally any topic – food, gaming, relationships, politics, work, you name it.

Why expanding brain never dies

Most meme formats burn out after a few weeks. Expanding brain has survived for years because:

  • Universal template: It works for any subject. As long as you can rank four things from normal to absurd, you have a meme.
  • Scalable: You can add more panels for extra escalation. Some versions go to 8 or 10 panels deep.
  • Self-aware humor: The format is inherently ironic. Everyone knows the “galaxy brain” take is silly, which makes it safe to be ridiculous.
  • Relatable: People love ranking things and making fun of overthinking. This meme does both.

“Galaxy brain” as slang

The meme gave birth to the phrase “galaxy brain” as standalone slang. When someone has a “galaxy brain take,” they have either proposed something brilliantly unconventional or hilariously terrible – and the context tells you which. It is now used casually in conversations, tweets, and group chats far beyond the meme itself.

How to make your own

  • Pick a topic with at least 4 levels of escalation – from sensible to completely absurd.
  • Make the last panel the punchline. The humor lives in the final “galaxy brain” reveal.
  • Keep it ironic. The dumbest option should be presented as the most enlightened.
  • More panels = more commitment. Use 6+ panels for maximum payoff, but 4 is the classic sweet spot.
TL;DR The expanding brain meme ranks ideas from basic to galaxy-brained, where the “smartest” option is usually the most absurd. Born on Reddit in 2017, it survives because any topic can be slotted in. It also gave us “galaxy brain” as everyday slang for brilliantly dumb ideas.
