Definition: A rain check is a slang term used to indicate that a person cannot accept an invitation or complete a task at the present time, but would like to do so at a later time.
Use case: You can use the term "rain check" when you need to decline an invitation or postpone a planned activity. For example, if a friend invites you to go to the movies but you are too busy to go, you can say, "Thanks for the invitation, but can I take a rain check?" This means you are declining the invitation for now, but you would like to do it at a later time. Similarly, if you are unable to complete a task or meet a deadline, you can ask for a rain check to complete it at a later time.
