敢上课睡觉的女汉子
[găn shàng kè shuì jué de nǚ hàn zi]
It translates to 'the bold woman who dares to sleep during class', emphasizing a tomboy-like bravado or unconcerned attitude. In Chinese culture, sleeping during lessons typically isn't respected; calling oneself this might indicate toughness and defiance against convention.
