Closed mouth fang

There needs to be a tag for when a character's fang sticks out of their closed mouth. It's not a relatively common visual among the fang tag. The closed_mouth tag is in very limited usage, and could be used in combination with the fang tag, but that search would be crowded by group images if it's ever fully populated like open_mouth. Any preferences on how to tag it?

I'd be for fang_out, from tongue_out, though the latter is regardless of the mouth's openness. I doubt there's an emoticon for a "fang over lips".

I've gone ahead and started it as fang_out, since that seems fine to me.
