Brainboobitis 

A neurological condition in which a woman's brain migrates to her breasts. This results in the patient having large boobs and empty space where her brain should be. This is the official medical term, but is more commonly referred to as air head or ditz when applied to a woman with big tits.

Friend: That hot girl at taco bell turned out to be fucking stupid.

Me: She suffers from brainboobitis.

Friend: Oh, I see.

brain ghost 

A figment of one's imagination which occurs as a result of one's brain filling in gaps in information unnecessarily.

They can be sights, sounds, tactile sensations, or even an uncomfortable feeling a presence. They are distinguished from ordinary hallucinations by the fact that all people are prone to these phenomena, and the person need not believe the brain ghost to represent reality, although some do.

A person's blind spots are an example of a brain ghost.

"I was alone in my house when I felt the presence of a ghost."
"Ghosts don't exist; it must have been a brain ghost."

"I thought I heard a baby crying, but upon realizing that I was alone, I realized it was a brain ghost."
