The Indonesian phrase “kepala batu” literally means “stone head.”

If you call someone that, you’re essentially saying they are super stubborn or a total hardhead.

It’s used for that person who:

• Never takes advice or listens to anyone’s warnings.
• Insists on doing things their way, even if it’s obviously the wrong path.
• Is totally inflexible—you can’t change their mind for anything.

Think of it as the Indonesian version of calling someone a brickhead or pigheaded in English. Their head is just as solid as a rock!
