The phrase "to bounce back" means to recover quickly from a setback, disappointment or loss. It refers to the ability of an individual or group to rebound and regain their strength, resilience and determination after facing adversity. The term is often used in sports when a team loses a game but comes back strong in the next one. In life, it can refer to someone who has faced hardship such as loss of job, breakup or illness, but manages to pick themselves up, dust off and move forward with renewed hope and determination.
