A moronic message board poster who post insults and other ridiculous things just to piss off other users. Their posts never relate to the topic and they're always trying to change the subject(unlike flamers, who insult others while staying on topic). Trolls may sometimes have multiple accounts because they keep getting banned or they want to hide their identity. Even, so they're still pretty annoying.

Some people who harrass, insult and hurt other people on the internet which is usually on message boards...

A Good Example is the "Furrie" war on youtube where "trolls" are hacking , spamming and harrassing anyone who loves animals...
"Trolls" have no real reason for doing this and only do it for their own entertainment... Trolling is usually hated by many people and this has become quite serious...

In the process of trying to annoy someone,but the joke is only for you. It involves being annoying and pestering someone for large periods of time. Usually repeating the same words or phrase multiple times, lying in a pattern in hopes the person will think your telling the truth.

"Troll" means someone who causes unpleasant mischief. Trolls post inflammatory questions, comments or answers, or even create questions/comments/answers pretending to be someone else such as a young user.

These malicious people have their fun, get reported, get banned, then created a new account and come back.

Many people are trying to get users to completely ignore trolls so they'll get bored and go away. But plenty of people still allow themselves to get angry and post angry responses -- which of course is sweet bliss to the troll.

Alternatively, a "troll" means someone who's older and on the lecherous side.
"What is the best firearm for hunting down homos at your local mall? A 44 auto mag is too hard on the ears."

"GTFO Troll!!!"
