倌人
[guān rén]
In ancient Chinese contexts, it typically refers to a host, attendant, male prostitute or entertainer serving guests (mainly men). Nowadays the term is seldom used due to its outdated and specialized nature; however, using it as a nickname could hint towards characteristics like being social, charismatic, welcoming, versatile in entertainments and services, yet potentially carries connotations of superficial interactions and transient connections.
