美人称霸
[mĕi rén chēng bà]
A straightforward username that combines '美'(beautiful)'人'(people or person) which could refer to a beautiful individual or more generally a notable/decent/lovely human, with '称霸' (cheng ba), which means 'to dominate'. So the name can mean something like ‘A beautiful one will rule’ or ‘The lovely one reigns supreme’.
