WHAT ARE THEY SAYING-the one saying "He## yeah!"... or gibberish??

I think much of the "talking" is just gibberish and I find it hilarious, but one kid/guy yells what sounds like "Hell, yeah!" a lot and I know thats not what he's saying and it's driving me NUTS to not know what he is in fact saying! It's obviously real English words. I mean I think.... Help, anyone? just suggestions even! Anything to get the "Hell, YEAH!" out of my head!

Please, someone? I'm being serious. I don't know if it's against the rules to write "hell"..probably not...but if you play any of the Moai's you've heard it! It could be "help, help" I suppose but it doesn't really sound like it. I know it's a small thing, but it drives me crazy!
