An informal term for a crazy person or eccentric — someone whose behaviour is erratic, unpredictable, or wildly unconventional. Used more affectionately than pejoratively in many contexts, especially among friends. The '-head' suffix is a common English slang formation used to describe people defined by a particular trait.
