daddy's boy
A gay thing where a grown man acts like a tough older guy and a younger guy is his obedient little pup. They might even play dress-up and spank each other.
Dad: 'You're grounded for saying your teacher is ugly.' Boy: 'Yes, sir.'
He let him wear his old clothes and called him 'my little lamb.'
They did a whole thing where he spanked him for eating the last pizza.
