[Sarah]

One who purposely and deliberately (that purpose usually being self-amusement) starts an argument in a manner which attacks others on a forum without in any way listening to the arguments proposed by his or her peers. He will spark of such an argument via the use of ad hominem attacks (i.e. 'you're nothing but a fanboy' is a popular phrase) with no substance or relevence to back them up as well as straw man arguments, which he uses to simply avoid addressing the essence of the issue.

[Sarah]

One of many unsung internet heroes who are almost entirely misunderstood. Contrary to popular belief, many trolls are actually quite intelligent. Their habitual attacks on forums is usually a result of their awareness of the pretentiousness and excessive self-importance of many forum enthusiasts. As much as people may hate trolls, they are highly effective - their actions bring much of the stupidity of other forum users out into the great wide open.

[Sarah]

A dumbass who makes idiotic posts in message boards newsgroups for the sole purpose of pissing people off, often lacking in intelligence. Sometimes compared to people who pass you by on the sidewalk then grab you in inappropriate places.

Before the Internet, there were the mythical Trolls of old who ate farmer’s goats.
After that, there were and are the semi-human versions of trolls that still exist today in all regions throughout the world.
Trolls can be divided into groups depending on where they live, such as Beach Trolls, Hill Trolls, City Trolls, Suburban Trolls, Valley Trolls and a couple other categories which take on unique characteristics depending on their surroundings.
All trolls are socially predatory creatures and when young are usually obsessed with their exterior appearances, while neglecting development of their blackening souls.
Their interior ugliness comes out as they age, and they, usually, let their outer appearances go to hell, so that they are easily recognizable. But, the young and middle-aged trolls will sometimes fool you with their charm.
All trolls are shysters and tight-fisted money grubbers who will screw you on any deal while making it out like you are the one coming out ahead. They will usually always greet you with a smile and a handshake. Sometimes, they will call you “brother” or “lady” to throw you off track.
All trolls are shit stirrers, lechers

[Sarah]

Someone who is purposefully posting on a forum/messageboard/site sith the sole aim to irritate the regular members.
Contrary to popular belief there is much more to internet trolling than posting OMG UR ALL SO GHEYYYY!!!1 OMFG TRIVIUM SUX ASS U FAGS LOL and the like. People who post such things will usually be one-post wonders and get banned, however the more experienced troll will attempt to cause some sort of havoc under the admins radar.
Common examples of trolling:
The long-term troll:
These guys dont mind waiting around for the fun to begin. They may pretend to be an average n00b, and give themselves the stereotyical interest(s) of the average member of said forum, then once having a few posts they will gradually try to spread dissent. This type may even pretend to be pally to the admin and get their msn (and try to crack their account password of course) whilst causing general disruption. May act under other proxies and slate these fake trolls on msn to the aforementioned gullible admin. These people, to be frank, usually have no life and love bringing message boards to their knees by putting considerable time into their carnage. If they crack the admins password the board is doomed.
The sophisticated troll:
This type will usually have some sort of distaste for whatever the said message board is discussing and try to cause annoyance as opposed to destructiveness. They will parody the members and see how much they can get over their heads. Subtle pisstaking being their route. Theyll usually get banned in the end but will annoy an entire community using this drawn out approach.
The faker troll:
A clever troll, the main aim of the game is to, ironically, act really REALLY stupid, this trolls aim is to argue with members incoherantly, usually using text speak. This is a ploy, the troll only needs to spend 10 seconds writing the babble when the member wastes 10 minutes writing a much more wordy reply. The troll will reply with a stupid rebuff making the member post as many long replies as possible. Using the members weight against them and wasting their forum time... If they are good then their act will be believable and they probably wont get banned unless the admin is strict on txt tlk.
The rank and file spammer:
These are the first to pop into peoples minds, they are similar to the examples stated in the first paragraph. No previous experience necessary, this lot will swarm in, again, usually under proxies to maximise the destructiveness, and spam the place to hell. Only causes mild irritation if not in large numbers.
Join any popular forum for a year and I guarantee youll see all of these.
