社会二姑
[shè huì èr gū]
In Chinese internet slang, 'social second aunt' ('社会二姑') often describes a woman who behaves in an unconventional, bold or somewhat out-of-line manner. It is used to describe people who act in exaggerated ways, sometimes breaking social conventions with their actions or words. This nickname conveys some humor, as well as the characteristics of being lively, naughty, and not conforming to norms.
