I am honestly kind of surprised this is not already a tag to be honest. Can make threads much cleaner looking when they are image intensive, or allow you to discuss shows and things like that without ruining it for those that may be currently watching it and not quiet caught up on it.

I suppose I could see how it could get a little out of hand if people decided to be a smartass and tag everything they say, or people combine together to troll a topic with said tag but I kinda think the positive side is more beneficial than the negative.
