You are only a good troll if you are witty and comical, and your material is ever-changing.
Most "trolls" of pimd just say the same tired nonsense to everyone they wish to fuck with. From what I've seen is it's usually a poor excuse for an insult. Or some childish mockery.
What is funny to me is any 1 random noob can laugh or agree and they feel "accomplished"
Not to ney-say, but the term troll almost directly matches the description of what the fantasy/fairy tail troll would be.
