"In Internet slang, a troll ( /ˈtroʊl/, /ˈtrɒl/) is someone who posts inflammatory,[1] extraneous, or off-topic messages in an online community, such as a forum, chat room, or blog, with the primary intent of provoking readers into an emotional response[2] or of otherwise disrupting normal on-topic discussion.[3] The noun troll may refer to the provocative message itself, as in: "That was an excellent troll you posted."
And no one does it better than Ramps.
