傲娇女子
[ào jiāo nǚ zi]
In Chinese internet slang, '傲娇 (ào jiāo)' refers to the personality trait of someone who is cold or distant on the outside but affectionate or soft-hearted inside. '女子 (nǚ zǐ)' simply means a girl or woman. Therefore, this username likely implies an independent, slightly standoffish woman who's actually warm on the inside.
