You know that expression/hand gesture where some character (often in anime) where they stick out their tongue and take a fist to soft bump their head? It's like a companion trope to face palming.
Five hats means that five tropers think it is ready to publish.
You are saying that you think this draft is ready to be published. That means the description is not ambiguous,
it doesn't duplicate an existing trope, there are at least three examples, and the title makes sense.
