Pro-Troll

A lot of people think, swearing every second word makes them a good troll.
What is YOUR definition of a good troll?

A good troll is one who-rather than simply getting everyone to tell him to stfu-manages to manipulate the forum into flaming itself. A good troll tricks other posters into drawing the ire of their fellows, starting a flamewar that has the potential to rage on for pages and pages with few (if any) additional posts from the troll himself.
