Tiggerdooley, you are a troll if you post a provocative bit of fluff and sit back to watch the fur fly.

Example: I heard that Spaw likes to blow up the butts of small woodland creatures.

You are a flamer if you post something that attacks someone. (Note the exclamation points)

Example: Spaw couldn't play an oppossum if it were made of clay and hollow!!!!

All others are genuine. It boils down to intent.
