Noun- The troll's counterpart, analagous to a hero's antihero. To put it briefly and bluntly, trolls try to make you look like a pussy; antitrolls try to make you look like an asshole.
To further explain:
The common troll seeks to sow discord and negative emotion among an otherwise peaceful (may or may not be intelligent) dialogue, which is usually held on an Internet thread or message board.
The common antitroll attempts to inject logic and positive reasoning into an otherwise hateful (may or may not be unintelligent) collective diatribe, also usually held on the Internet.
However, note the three characteristics both have in common:
1. Both are contradicting the purpose of the thread they target, and quite often don't care about the topic itself.
2. Both are commonly the subjects of hatred for doing so; they also enjoy this hatred.
3. Both usually have nothing better to do with their lives, at least during the actual troll/antitroll session, and know that their efforts won't change anyone's opinions/views. It's just for the lulz (trolls)/ to pass the time(antitrolls).
