What does it mean to be called a pig head by a girl?

At first, a girl called me a pig head, which was quite puzzling. She thinks I am stupid.

Actually, no, she likes me, hehe.

This is the name of love. If he often calls you a pig's head, she must like you, but she is afraid to say it.

I wish you an early marriage,

We're breaking up now

I hope my pig head can come back,
