No, not like that. Put some feeling into it!
Now you just sound like you're in pain. C'mon! This is supposed to be a cheer! Now - Gimme an OH!
Gimme a SEE!
You call that a see? You did the oh really well. They have to sound the same. Hit it hard - maybe if you take a deep breath before you yell, you can give it that nice sharp edge. Okay - Gimme a see!
Okay, gimme a DEE!
Fine. If you're going not going to even TRY to get it right, don't bother.
