Smooth brain

Smooth brain is an insult that refers to an unintelligent person. Supposedly, the intricacy of one's knowledge is represented by the wrinkles on their brain. If their brain is smooth and lacks wrinkles, their knowledge lacks intricacy, and they are therefore stupid.

What a smooth brain that person is.

brain

Something that the majority of the human population lacks, despite having evolved to increase its size.

Humanity is quite stupid. This is because TikTok removes people's brains.

Tooth infection that spread to my brain

Is why I feel drained. I took some antiseptic mouth wash and it ameliorated my symptoms by 30% overnight.

Hym "And if I could prescribe myself with antibiotics for the tooth infection that spread to my brain I wouldn't feel this way."

brain fever

(noun) A belief that "crazies are great in bed." Coined as a parallel to "yellow fever" for fetishizing Asian women, "jungle fever" for fetishizing Black women, etc.

It's not always easy to distinguish someone with brain fever from a partner who's merely willing to support you through your mental illness.
