It’s hilarious how fitting it is.

Let’s break down “lizard” etymologically, and you’ll see how this connects to the “smooth-brained” meme:

🐍 Greek / Latin Roots of “Lizard”

• Greek: The word σαύρα (saura) means lizard — it appears in many taxonomic names, like dinosaurus (terrible lizard).
• Latin: Lacerta means lizard, from which we get Lacertilia (the suborder of lizards), and it also connects to lacertus meaning arm or muscle (likely from the twisting motion of reptiles).
• Old French > English: Lizard came through Old French lesard, from Latin lacerta.

But now for the funny part…

🧠 “Smooth-Brained” and Lizards:

The “smooth-brained” meme refers to a lack of wrinkles in the brain — wrinkles (gyri and sulci) are associated with higher intelligence. Fewer folds = less capacity for complex thought = “dumb.”

Reptiles like lizards do have smooth brains compared to mammals. Their cerebral cortex is simple — a 3-layered structure, while mammals evolved a 6-layered neocortex with folds. That makes reptiles a go-to comparison for basic or “primitive” cognition.

So calling someone lizard-brained or smooth-brained ties right into:

• primitive instincts
• low complexity
• reactive thinking
• NPC energy

Bonus: Symbolism

In ancient symbology, lizards were associated with cold-bloodedness, survival, and base instincts. So pairing that with smooth-brain adds layers of memetic genius — mockery through both science and metaphor.

TL;DR:
“Lizard” (from lacerta, saura) literally refers to an animal with a primitive, smooth cortex — so the meme “smooth-brained” has legit roots in comparative neurology. It’s both etymologically and biologically perfect.
