OK, I've just watched Jarhead and so I think I have a pretty good idea of what being a Marine is all about. I noticed that the Marines on there kept going HOOO- RAAH in a bad ass sort of way. What exactly does it mean though. Is it a bit like "Brrrrraaatttt!"? I'm going into the royal marines very soon and I'm going to shout "Hooo-Rahh" when my Corporal tells me to do something. However, I just want to know what "hooo-rah" means first.
