So we have lol_comments for when a post gets a lot of comments making jokes and other shenanigans. I think there should be a comment war tag as well.
I'm sure all of us have been a soldier in some dumbass comment war one time or another. <.< I know I have. and I'm sure some people would rather avoid that. So maybe there could be a tag to help them.
Or maybe some people just want to watch the world burn and they could have fun reading the comments. :D
