As demonstrated in post #290125 and others like it, it seems "assless" panties could use a tag. The problem is that the most obvious one, "assless_panties", seems like it would reinforce the mistaken "porn site" identity (I'm sure we don't want another "pussy_juice"). On the other hand, it might be impractical to soften it because it's going to be a tag that will by and large service questionable or explicit posts, and calling it something cryptic would render it less useful as a tag. Any ideas?
EDIT: How I got away with using "implicit" instead of "explicit" on Danbooru, I'll never know.
