On Twitter, fans banded together by using the names of their favorite characters, and the phrase, “mischief managed.”

 The phrase is a reference to the Marauder’s Map, a magical document that reveals all of Hogwarts School’s secrets. To view the map, one must tap it with one’s wand and say, “I solemnly swear that I am up to no good.” To make the parchment appear blank and hide the map, one must again tap it with the wand again and say, “Mischief managed.”

On Facebook, fans promised to raise their wand (or hand) when the credits of the “Deathly Hallows” began to roll, and say the phrase with confidence.

On Twitter, Lord Voldemort made this mischief:
