乖乖女耍流氓
[guāi guāi nǚ shuă liú máng]
This nickname combines contrasting elements: '乖乖女' (good girl) and '耍流氓' (acting like a hooligan). It plays on the stereotype of a well-behaved girl breaking out of her usual demeanor, maybe embracing a wilder side or acting out against society’s expectations. This name could also suggest the irony of defying norms.
