A fanonship from Avatar: The Last Airbender that ships together Zuko and Katara, who never showed any romantic interest in each other. Despite the fact that it's been proven as crack and never became canon, many continue to rabidly ship it, under the delusion that it "should have happened", and hating the show's creators for not granting their wishes.
"Kataang is pedo because of their two year age difference, but the three year age difference in Zutara means nothing!"
"Whatever, you know Zutara should have happened. Why? Because I said so."
