你没胸凶什么凶
[nĭ méi xiōng xiōng shén me xiōng]
The user name 'You Don't Have Big Chest, What Makes You So Hostile?' plays on the word '凶 (xiong)' which sounds like '胸 (xiong) meaning 'chest'. This is a sarcastic and humorous remark, possibly used by someone who doesn't want others to be overly aggressive without reason.
