Harry Potter and the Prisoner of Azkaban2003

[Hermione sees Malfoy laughing about Buckbeak, Hagrid's hippogriff, being executed that night.]

Draco Malfoy:
[to Crabbe and Pike] Father said I could have the hippogriff's head. Maybe I'll donate it to the Gryffindor Common Room.

Crabbe:
Look who's here.

Draco Malfoy:
Ah! Come to see the show?

Hermione:
[furiously] You! You foul, loathsome, evil, little cockroach! [holds Malfoy at wandpoint]

Ron:
Hermione, no! He's not worth it!

[Hermione relaxes and takes her wand away from Malfoy, but almost immediately punches him in the face. He and his gang run off, panicking.]

Hermione:
That felt good.

Ron:
[impressed] Not good. Brilliant!
