Perhaps its creator had in mind both being aghast and the sputtering sound made by people who are so amazed, they can barely speak. To flabbergast is to shock, so some events that might flabbergast you include winning the lottery, hearing that your best friend and his family moved to Switzerland yesterday without telling you, or getting stuck in a snowstorm in April in Texas.
