表面朋友
[biăo miàn péng yŏu]
It means 'Superficial friend'. In English-speaking contexts this concept refers typically to acquaintances - the term suggests someone you are friends with on the surface level but not particularly close or intimate. Someone with this moniker could be cynical about human relationships only stopping at a superficial interaction level, or might just describe themselves objectively based on how they view their social circle or personal connections.
