In Internet slang, a troll (/ˈtroʊl/, /ˈtrɒl/) is a person who sows discord on the Internet by starting arguments or upsetting people,[1] by posting inflammatory,[2] extraneous, or off-topic messages in an online community (such as a forum, chat room, or blog), either accidentally[3][4] or with the deliberate intent of provoking readers into an emotional response[5] or of otherwise disrupting normal on-topic discussion.
