A mental state in which a person has become so accustomed to porn they prefer porn to sex, buy expensive content and actually go so far as to click on the ads for herbal remedies that increase dick size. If porn brain persists it may result in fap out while prolonged video buffering can cause homicidal rage.

Must have porn brain.
