Our reading
An editorial interpretation.
These are the words that hide the Marauder's Map once its user has finished with it. In Prisoner of Azkaban, Fred Weasley teaches Harry how to clear the parchment again. Two words make the secret adventure feel neatly complete: trouble has been had, and the evidence has vanished. Outside the story, fans use the phrase as a playful sign-off for a plan successfully carried out.
