In internet jargon a "troll" is someone who posts commentary intended to provoke a strong reaction. Trolls can range from the obvious (obscenities, slander, rudeness) to the more subtle (well-phrased but flawed arguments.) The best known way to deal with a troll is not to "feed" them, that is to say, deny them the reaction they desire. As a result, dedicated trolls have had to become very skillful in couching their trollish behavior within seemingly innocuous correspondences. Since trolls have become more and more subtle, it is sometimes difficult to tell if someone is genuinely expressing themselves, or simply trolling for a reaction. Someone who "smells a troll" suspects that they may be unknowingly feeding a troll.
