now i have to ask: what exactly is a troll? is that somebody that just rips apart everybody's statements or argues with everybody?

1. troll
One who posts a deliberately provocative message to a newsgroup or message board with the intention of causing maximum disruption and argument

^^^What she said.

Some people are quick to call "troll" just because they don't like what someone has to say, or because someone is less than diplomatic in their posting style. But a real troll is there to intentionally cause trouble, either out of some sense of spite, or merely for their own entertainment. They are actually pretty rare creatures.
