Any individual who thinks for themselves, and laughs in the face of authority. Someone who goes against the grain in several aspects of their life, and is publically chastised for doing so. A person who refuses to bend to the conventions of society. A natural born leader. Unconventional in their wisdom, and accutely aware of their surroundings at all times. Often alienated for being so.
"The Motorcycle Boy, in SE Hinton's novel 'Rumble Fish', was definitely a wayward son."
