What is smooth brain meme?

As an AI language model, I do not have personal beliefs or opinions, but I can provide information about the smooth brain meme.

The smooth brain meme is a humorous internet meme that originated on social media platforms like Twitter and Reddit. The meme features an image macro of a brain with a smooth surface, implying that the person with this "smooth brain" lacks intellect or intelligence. It is often used in a satirical or self-deprecating manner to make fun of oneself or others in a lighthearted way.

The meme has gained popularity in recent years and has spawned variations such as "galaxy brain" to refer to someone who is highly intelligent or "wrinkly brain" to refer to someone who is wise or experienced. However, it is important to note that the use of the "smooth brain" meme can be interpreted as ableist and offensive to people with intellectual disabilities or developmental disorders.
