Not cyberbullying.

Some people do horrible things that can make others depressed or even commit suicide. They call themselves trolls, and the media believes them, but they aren't trolls. They are cyberbullies and horrible people. Good trolls can make both people laugh in the end.
Person 1: I just sent someone death threats because they said something I disagree with! Trolling is so great.
Person 2: You aren't a troll. You're just an asshole.

Posting rude and distasteful comments, sometimes for the purpose of a reaction and other times not. Either way it is malicious and whether it is intended or not can have serious consequences. Those who troll will laugh at that, but trolling fosters an environment that leads to more serious abuse also known as cyberbullying where lines are crossed which should never, ever be--like encouraging someone who is suicidal to commit suicide. This is bad humor, and while in your virtual reality it may be funny, in actual reality it's not. It's time to grow up.
See YouTube.com for endless examples of trolling.

When ones phsycological state and disconnections with other humans makes it acceptable to invoke a response from someone via the internet, typically with an emphasis on (one of the following)

a. trying to assert ones dominance over the other
b. attempting at ones very best to gain attention

This person is typically the individual in which has little, or no friends and doesn't know much about compassion. You can also get the rare troller, whom doesn't fit any of these categories, and does it just for fun. The way to distinguish them is to pay attention to their trolling habits and how they communicate with other people. If you notice an extreme emphasis on either a or b(above) than you've got yourself someone with little or no knowledge on how to have a correct encounter with another human being.

You can never really find a troll in real-life, or if you do it'll be in the drive through or he'll be getting picked up by a relative(as he doesn't drive.) Most trolls prefer to reside in their place of trolling, typically a basement with a internet connection.(Any isolated environment from other humans.)
No example can correctly pin-point the disease of the Troll.

If you're looking this up, for whatever reason you decided to look this up; you've probably got a troll.(trolling)

The act of being bothersome or annoying to a group of like-minded people, usually with casual opposition, rather than sincere opposition, to those people's ideals.

Also, usually done over the internet.
