From the MBTI personality test, which went viral on Chinese social media in 2022-2023. The first letter of the type (I = Introverted, E = Extraverted) became shorthand: i人 / e人. Asking 'i人还是e人?' is now a standard icebreaker.
usage
Read the letter i in English as 'ài' and 人 as 'rén'. The opposite is e人 (yì rén, extrovert).
