Small Brain

When people have a small brain, they are not smart. In comparison, their brain is at least 2 times smaller, but in rare cases can be even smaller. Small brains usually: are brown haired, play volleyball, have a twin, named Madison.

Who’s that?
Oh that’s Madison, she’s a small brain.

Aw, poor thing.

Small Brain

When taken almost literally, it means someone is unintelligent or unequipped to talk to a specific person or about a subject. Although it has ironic connotations to mean that the interlocutor or the person they are speaking with is on another level/wavelength.

Compared to my friend, big brain Bojack, who is simultaneously discussing Kant's Deontology and Quantum Mechanical superposition, I have a small brain.
