The phrase “Rebel Without a Cause” refers to someone who rebels or challenges authority, social norms, or expectations without a clear reason or purpose. It describes a person driven by inner conflict, frustration, or a search for identity rather than by a specific cause or injustice.
The term became famous from the 1955 film Rebel Without a Cause starring James Dean, which portrays disaffected youth struggling with alienation and misunderstanding in postwar American society. Since then, it’s often used to describe aimless rebellion or teenage angst.
