HYAKY!

I have no idea what this means, but the word means challenge to my babes. And not just any challenge, more specifically...One says "HYAKY", if the other accepts the challenge they lay on the floor and the challenger then repeatedly jumps over the one on the floor shouting "HYAKY" until the challenger then sits on the "victim's" back...claiming victory, no less! We now have a HYAKY stick we jump over made from Duplo blocks and occasionally challenge Elmo and other large animals in the house. Can you tell we've been indoors too long? Oh...if Hyacky means something horrible in another language, please forgive. I really have no idea where they got it from!
