A despicable person on a message board that deliberately tries to get everyone pissed off. Usually, they write in capital letters and make outrageous topics to get a rise out of everyone. Many times, trolls will be regulars but cannot be identified because they make new Screen Names, usually these new Screen Names are named after the topic they're trolling about. Either way, trolls should never be responded too, because theyll just use insults or useless arguments, and you'll never win by arguing with a troll.
Don't ever feed the trolls on a message board.

Cannibalistic Ogre from mainly Scandinavian Folklore. Hairy, longnosed, brutish and Bug-eyed, they may also have multiple heads or horns. They come in all sizes, and either burst or turn to stone when sunlight hits them. They lurk in gloomy forests and dark caverns, and especially like to devour small children. However, they are usually pretty thick and can be outwitted with clever tricks.
The Females of the species are generally kinder and more intelligent, but still fairly hideous.

Gretir fought one.
Moomins are nice versions.
Gonks are sometimes called Trolls
Billy Goats Gruff are well known Troll Slayers.

A person who posts rude, off topic, or other twisted comments in the name of angering people. There are 2 types of internet trolls though. Troll is a shortened version of the term Troller, that means the same thing.

Bad troll: An idiot who can't win in arguments in real life, so he goes on the internet and posts random bullshit to make himself feel better about being a moron. You can usually find these on chatrooms like AIM and comment boards like on Youtube. The also troll other comment boards like aol news (espicially kidnapping cases since they try to look like they did it to look beast)

Good Troll: Rare, but still in large numbers. These are similar to bad trolls but do it for the good of getting idiots off the web, such as trolling someone on Youtube who posts everything their dog does or someone acting tough with a keyboard. Think of it as the Asassain's Creed story, The good trolls are the Asassains and the morons and bad trolls are the Templars.
Example: Good troll finds bad troll and they fight.
Bad Troll(on a kickass mw2 knife kill) OMG NURD GO PL3H BFBC2 IS W3H BETTER TAHN THIS YOU EAT DICK N00BER!!!!
Good troll: Bad Company 2 hasn't come out yet :D.
Bad troll: STFU your a retard i'm going to kill your family.
Good Troll: Good luck E-thug....

Example 2: Good Troll finding someone taped there dog pooping and posted it on YT.

Good Troll: A little privacy for Muffy here would be cool?

Creator: OMG REPORTED LOL U FAIL!

Good troll: ..... youtube doesn't have a report function nor do they give a crap about you and me.

Creator: OMG NO NO I FOUND IT YOUR BANNED!!

Good troll: Idc.

"Socialism is a fatally flawed ideology that has utterly failed the people it purported to help."

POST #2 (Troll)
"Well of course it did to a racist, sexist, bigot, homophobe like you. You and the other Chimpy McBushhitlerites probably want to grind up the lazy ass poor people and turn them into dog food! My food doesn't have parents. Meat is murder!

Likewise some workaholics are obscenely rich and it's not fair. The money that they have personally stolen from the Native Americans since 1492 should be taken away and given to the lazy ass poor people (so that they can become lazy ass middle class people). And what about WMDs and global warming? What about those, huh?

MEAN PEOPLE SUCK so I hope you eat a lot of fast food and die of a heart attack! Fascist bastards!"

POST #3 (Moderator)
"In an effort to raise the collective I.Q. of this site, Troll, you are hereby BANNED! Now go take a bong hit to calm your apoplexy."

Rhymes with 'stroll', it refers to a style of fishing where a baited line is drawn in front of fish hoping that one will bite. The person doing is a troller.

The analogy to a baited message hoping for bites is obvious.
