In the film version of Harry Potter and the Goblet of Fire a huge melee breaks out at the site of the Quidditch World Cup and a group of Death Eaters march through the campsites, burning them to the ground. There's a tiny bit where we see the Death Eaters walking through the campsites with torches, chanting something.
What are the Death Eaters chanting as they're burning down the campsites at the Quidditch World Cup?
I'm a native English speaker and the chanting truly doesn't sound like English to me, for what it's worth. Also, I did check the site to see if this question has already been asked and I couldn't find that it has. My Google-Fu skills apparently suck today, meh. I'm pretty sure J.K. Rowling hasn't addressed this; she tends to prefer talking book canon.
