You have to make the accompanying hand gestures, which I can only describe as kinetically emphasized whining.

The more he wants to whine about something he detests, the more he uses his little hands to make little motions, like they're an exclamation point for how annoyed he is.

This is opposed to say, emphasis for dramatic effect, to convey conviction, seriousness, passion, anger, or something like that.

That's the part he did not manage to learn from his nightstand collection of Hitler's speeches.
