倾国倾城倾美人
[qīng guó qīng chéng qīng mĕi rén]
This online name combines three elements: '傾國' (a term meaning beautiful enough to ruin a country), '傾城' (beautiful enough to overthrow a city), and '美人' (beauty). It means someone is incredibly beautiful or attractive, almost supernaturally so. This comes from traditional Chinese admiration for extreme beauty in historical contexts, like legendary beauties who caused kings to act foolishly.
