A sad person who gets a kick out goading an innocent person then calling this person a keyboard warrior
! When in actual fact the person being goaded is just reacting to being called something derogatory and\or insulting!
Usually this is done through the text-based medium of the internet
and usually under the cover of humour
and usually split between threads or conversations to mask the accusation.
Person1: Hey you're an ass lol!
Person2: What? Did you just call me an ass? What the well you're a bigger ass! Was that supposed to be funny?
Person1: Omg you're such a keyboard warrior
Person 1 is a keyboard warrior creator.
