Gryffindor is one of the four houses of Hogwarts School of Witchcraft and Wizardry in J K Rowling's Harry Potter books, first published in 1997, and in the film adaptation Harry Potter and the Philosopher's Stone from 2001. New students are sorted by the magical Sorting Hat, which calls out the chosen house aloud in front of the Great Hall. The house is associated with bravery, daring and chivalry, and its name alone became shorthand online for courage and loyalty. Fans reuse the shouted announcement for sorting quizzes, fandom edits and playful house reveals.
