傲气小祖宗
[ào qì xiăo zŭ zōng]
It roughly translates to 'proud little ancestor' or 'spoiled child with a haughty air', denoting a pampered individual who feels superior and has high self-esteem, probably reflecting the user’s confident and domineering personality, or ironically expressing oneself who tends to be somewhat naughty and uncontrolled but endearing.
