There is something for everyone in here!
http://www.urbandictionary.com/define.php?term=Internet+Troll&page=2My eclectic:
A person whose sole purpose in life is to seek out people to argue with on the internet over extremely trivial issues, with the primary intent of provoking other users into an emotional response or to generally disrupt normal on-topic discussion.
-can be male or female, mostly males, including the popular 'gender bender'44 year old man that acts like 14 year old girl.
Female internet trolls, are far more scary than their male counterparts. Female trolls seem better able to delude themselves into believing that their behaviour is not only accepted online but that the traits that they find so well received (they are not) will transfer well to real life.
A person who posts remarks or comments onto internet forums or message boards in an attempt to get someone to comment negatively to it and to redirect attention onto himself.
Sometimes, the comments are enough to enrage the people in the forum to want to respond back with their own negative remarks which starts a flame war and changes the topic and attention of the discussion.
Biased and angry because of envious or unreasonable emotions trolls will degrade you for even speaking or making any statement at all.
OK cats now lets play spot the troll!
