I just saw a troll as someone who says/does something to intentionally piss people off, but apparently, according to people at my college, I'm wrong. A troll to them is anyone that has an opinion other than theirs. For example, I said I find RTS games boring because all you do is collect resources, build buildings, build units, attack the enemy, and that I can't tell a difference between Starcraft and Age of Empires. He said that was trolling and that Age of Empires sucks. But, no, his saying AoE sucks isn't trolling because apparently it is true.
