This username means 'So handsome that it angers both mortals and gods, so beautiful that it can overthrow cities'. It is often used sarcastically or humorously by those who feel inferior to someone's appearance or charm. The expression combines Chinese hyperbole in describing beauty and attractiveness with a hint of jealousy.
