Smooth Brain

What does Smooth Brain mean?

Someone not very smart

When you hear someone being called a Smooth Brain, it’s a less than polite way of someone saying they’re not very bright. It’s a cheeky way of comparing them to an “idiot,” “dimwit” or “fool”.

The idea behind this term is based on the scientific theory that more brain folds correlate with higher intelligence. In this context, a smooth brain implies lack of intellect, similar to calling someone as dumb as a stone.

It’s common to come across the term Smooth Brain in online discussions, especially in playful or sarcastic arguments on social media platforms or Internet forums. A great example of its usage is within the Reddit community, specifically the subreddit r/investing, where members often humorously refer to each other as smooth brains.

Despite its casual usage, it’s worth noting that a smooth brain is actually a serious medical condition. This condition, known as lissencephaly, causes a child’s brain to develop without the normal folds. Tragically, most children with this condition don’t survive past their tenth birthday. So, while it may seem funny in the moment, it’s worth considering the real-life implications before using the term Smooth Brain.
