Definition

Prepare yourself for jail; a warning that someone is going to be arrested or imprisoned.

colloquialslangbody

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.

Examples

If you keep causing trouble like this, you really need to prepare yourself for jail.
He breaks the law all the time, he will have to prepare for jail sooner or later.

Common mistake

Do not use this phrase in a formal or professional setting, as it is extremely informal and can be perceived as aggressive or highly offensive. It is strictly a colloquial expression and should never be used to describe actual legal proceedings in a serious context.
