An Internet troll, or simply troll in Internet slang, is someone who posts controversial and usually irrelevant or off-topic messages in an online community, such as an online discussion forum or chat room, with the intention of baiting other users into an emotional response or to generally disrupt normal on-topic discussion.
How to handle it: Experienced participants in online forums know that the most effective way to discourage a troll is usually to ignore him or her - and report the post to the mods, because responding tends to encourage trolls to continue disruptive posts — hence the often-seen warning: "Please do not feed the trolls".
