我素萌萌哒女汉子
[wŏ sù méng méng dā nǚ hàn zi]
This nickname expresses a playful and affectionate self-description. 'I am super cute and lovely despite being a strong and tough girl' is how one might understand it. It’s an amusing blend where the person is asserting her femininity in terms of charm while calling herself a 'lady-man', someone strong or rough.
