你为毛这么叼
[nĭ wéi máo zhè me diāo]
The nickname 'You Wei Mao Zhe Me Diao' translates roughly to 'Why Are You So Arrogant?'. In the Mandarin language, '刁' usually means someone is naughty, arrogant or a troublemaker. It implies a kind of humor in expressing their character or state of mind, which often carries self-deprecating sarcasm.
