As you may know, all these types of places have similar trolls.
I am a fan of our local College basketball team. Long story.
As of now, they are #6 in the nation.
Anyway, they have a fan site with a forum. There is a troll there as well. I do not post much there as I am not skilled or actually know much about basketball. I wrestled in high school and college. Same season.
Anyway, heres a response to that troll by another person on that site.
He's a twit.

He's a dolt.

He's one taco short of a combination plate.

When he was a kid and his parents told him to put on his shoes and socks, he did it in that order.

When he has something worthwhile on his mind, it's generally a hat.

During evolution his ancestors were in the control group.

He's suitable for vegetarian consumption.
This basketball troll is somewhat more advanced then ours, he has a hundred different handles and often carries on a thread talking to himself. Of course, most posts about him are X rated. This was a nice one. Fits our troll
