驸马

Historically, this refers to the husband of a princess in feudal China. It has the connotation of being someone closely tied to royalty or nobility, and traditionally it also meant having a high status. Today, people who use it might do so either literally to identify themselves with royal ties, metaphorically to express admiration or humor about marrying someone 'high up' in status, or perhaps ironically, poking fun at certain social standings.
