高冷低能儿

Translating as 'High Cold Low IQ Child', which combines high-and-cold attitude, suggesting distantness or disdain towards many, contrastingly labeled oneself low-functioning mentally or emotionally, probably creating irony, humor or intentionally making fun of oneself's antisocial behavior and lackadaisical mannerism. Alternatively, a way to describe a cold aloof character who has less confidence about their intelligence or skills in some respects but does not want to interact socially due to personal reasons.
