My friends at school got me thinking.

At the shouting bit in the theme, at the start, what are they saying?

My friends thought it was 'Fus Ro Dah' which is clearly not the case as it sounds nothing like it and doesn't go with the theme of the song, but what is it they're actually saying?

For what it's worth, I don't hear any hard consonants, so I think 'Do Vah Kiin' is out.
