Ok I just down loaded video and watch it. Sounds like a pissed off grunt to me, kind of like when Dad said "hey jr", if I did not respond I got the one I would listen too.

Just like "the can" fate once everyone starts blowing it in the woods it will be useless IMO.

Atlas I think what Rob is asking is why all of a sudden is everyone hearing the "growl" now. Is because we have a name for it now, or is it all mental.
