Usually occurring in a Medieval setting, a king, duke, or what-have-you invites all the nobles of the land over for a banquet. Then, in the middle of the festivities, he has them all executed. The trope is not limited to this setting, though. It can be applied to any occasion when someone invites people to an event with the purpose of killing them.
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.
Is that what you meant to do?
You are saying this draft has a ready-to-publish hat it does not deserve and you are taking it back.
