Wheeeee-ooo, Wordwind! Memories of childhood. Haven't heard that in an age. (remember I am 73 so it was awhile ago.) My grandmother used it when frustrated with one of her seven boys as in : "Don't be such a dunderhead!"
Thanks for the memory.
I now await a chance to use it. As someone once said, "You may use profanity with impunity after you have mastered the English Language."
