How it's used
This is a highly idiomatic and sarcastic way to warn someone that their illegal or reckless behavior will inevitably lead to imprisonment. The phrase refers to the buttocks, as the number fifteen is associated with the full moon, which visually resembles the rear end. It carries a mocking tone and is used to dismiss someone's arrogance by reminding them of their impending loss of freedom.
