A free ride refers to a situation in which someone benefits from something without having to put in any effort or pay any cost. It can also refer to taking advantage of a situation or opportunity without contributing anything in return. This term is often used in a negative context, implying that the person is unfairly benefiting at the expense of others. It can also be used to describe a situation where someone receives a benefit or service without having earned it or fulfilling any requirements. In essence, a free ride is a form of unearned privilege or advantage.
