Quote from : Harry Potter and the Prisoner of Azkaban Movie

Malfoy: Ah, come to see the show?
Hermione: [shouts] You! You foul, loathsome, evil little cockroach!
[Hermione raises her wand at Malfoy. He backs against the wall, whimpering]
Ron: Hermione, no! He's not worth it.
[Hermione lowers her wand and turns away. Malfoy starts laughing, she spins around and socks him in the nose]
Vincent Crabbe: Malfoy! Are you okay? Come on, let's go!
Malfoy: [running away] Quick! Not a word to anyone! Understood?
Hermione: That felt good.
Ron: Not good, brilliant!
