Writers Brain 

This could be used to describe the brain of any writer, but i believe it to be a periodical and temporary experience. It is when someone is in the headspace of being poetic or saying and thinking beautiful, deeply emotional crap. It’s truly haunting. Non-writers don’t understand this, but it’s a flurry of emotions. It’s also motivation to want to write, which normally doesn’t result in writing anyways.

“I just want to be loved like a fairytale right now, i want someone to gaze into my eyes... oh shit... i have Writers Brain right now!”

Broken Brain Syndrome (BBS) 

Used to describe Trump and his followers that have a massive disconnect from reality and fantasy, the inability to tell truth from lies and to act and say idiotic things.

A mass of people with "Broken Brain Syndrome (BBS)" showed up without masks to protest the social injustice of being in quarantine, thereby prolonging the quarantine.

Cum brain 

When you’re in a mental state of horniness and you can’t think straight. Usually the stage before post nut clarity.

Sarah: *out of breath* Did you say you loved me?!?
Bobby: *also out of breath* Oh shit my bad I had cum brain. Sorry I wasn’t thinking straight.
