How it's used
This is a classic idiom often used in a self-deprecating or admonishing tone when someone realizes their lack of preparation or study has left them helpless in a practical situation. It carries a heavy sense of irony because the speaker is usually acknowledging their past laziness while facing a current consequence. It is frequently used to encourage students or younger people to value their education before they enter the workforce.
