"In Internet terminology, a troll is usually someone who enters an established community such as an online discussion forum, and posts inflammatory, rude, repetitive, offensive, off-topic or otherwise disruptive messages designed intentionally to annoy or antagonize the existing members or alter the flow of discussion, including the personal attack of calling others trolls. Often, trolls assume multiple aliases, or sock puppets."
