troll

Someone who posts nothing of substance to try and strike up emotional responses instead of true discussion or debate, usually because they haven't the intelligence or facts to engage in such discussion or debate. Phrases typically used by a troll are usually found between sentences where they state what little they know and add their attacks (i.e. "Suck it!", "Fail!", "You fail!"). Trolls are generally weak-minded people with a strong motivation to bring everyone down to their crude level of thinking. They seek out topics of the greatest controversy and try to infuriate anyone they can. The only way to deal with a troll is to delete his ass and ignore him. Beware some trolls have their own web sites where other trolls are permitted to operate. These troll havens are easily spotted, because no comments or posts are moderated.
