Is it weird for a girl to call a guy Hyung?

I have many female friends and nobody call a man generally hyung. Of course they can sometimes make a joke calling a man as hyung but it does not mean that the girl can call a man hyung .

Can I call my boyfriend Hyung?

It seems like the younger generation doesnt mind using this one term for a variety of relationships. In this light, hyung, or a boys older brother, can refer to both his actual older brother and his older male friend. Theres even an honorific form of this word, hyung-nim.
