挥刀男婊

It roughly translates to 'A man wielding a sword and swinging around wildly while having two-faced behaviors'. The word is a compound word, consisting of words meaning swinging a knife/weapon and someone who behaves hypocritically, especially males, often expressing anger, resentment, contempt, or satire toward such person by users. It's worth noting the expression is not particularly positive nor politically correct for general use.
