你又没胸凶什么凶啊
[nĭ yòu méi xiōng xiōng shén me xiōng a]
Loosely translated to 'You aren't well-endowed yet you're so mean? '. The netizen seems to tease or express dissatisfaction towards someone they perceive has no right to show their attitude, using a physical trait as an analogy for lack of qualifications.
