Over the past four months, I have been adding posts to a set I created. I'm using a set because I couldn't find a tag to describe these posts. Now there are over 400 posts, and I think the set should be made into a tag(s).

The set is: set #3880 (NSFW) _{(examples included)}

• Is there already a tag(s) for this?
• If not, would it be appropriate to create a tag for this?
• What would you suggest that tag be called?
