傲娇公举百变男爵

This elaborate name translates into English roughly as a 'proud and coy princess/baron who can change dramatically.' It might point out an extravagant taste for role-playing and expressing oneself with many different personalities. Note that '公举' here is likely a blend or typo for '公主'(princess) in Mandarin, but also sounds playful like the way a spoiled kid would say, adding cuteness.
