Tce coined this sound-word to be used when you were puzzled by something someone said. It was the equivalent of "huh?" I later added a transnomatopoeia definition to it by describing it as the imaginary sound made by your pet dog when it cocks its head sideways at you quizzically. I specifically defined it as a pet dog as a tribute to Tce, who was born in the Year of the Dog. In common usage, it is not set off by asterisks.
