Prompt a ship. Any ship. A ship you like, a ship you hate, a ship you don't understand.
Someone else writes a fic for that prompt in the comment. But only write fic for ships you don't ship. They don't have to be ships you hate, just ships you don't typically ship yourself.
But: don't bash the ship. Try to be fair to it. If you think it's messed up, you can explore that, but do it in a not-bashy way. I realize the line might be fuzzy, but use your best judgment, okay? I trust y'all.
