Keyboard warrior
来自China Digital Space
jiànpán xiá 键盘侠
Pejorative term for people who are quick to express a willingness to fight for a cause on the Internet without displaying the same commitment in the real world.
While previously existing in the online vernacular, the term "keyboard warrior" gathered attention when it was used in a commentary by the People's Daily following the fatal beating of a woman at a McDonald's franchise in Zhaoyuan, Shandong in May of 2014.
