Literal translation: 'Tough outside Soft inside Woman Paper' (Note: Here 'Paper' is likely a typo of 'Man'). Intended meaning: 'Tough on Outside but Soft Inside Female Guy'. It's often used to describe a strong-willed yet sensitive woman. A term used lovingly and humorously towards women who are both physically strong and have a softer heart inside.
