The troll is a idea of a person that is flagrantly obvious. For instance, if a hobo was to hold out a cup and say "spare change sir" the troll would reply "Why, no thank you, I have enough money." Trolls are truly the treat of the internet. If you go to any chat room, you will most definitely see a troll trolling himself away! The troll is such a popular meme that it even has its own anthem!(not official, for we cant ask the owner of the song. He is dead).
