<p>I've noticed that the characters of the show often grunt as a general affirmative reply. They most often use it in serious situations. In >THIS< clip alone, Steven grunts at 1:40 and Garnet does at 2:25.
</p><p>I haven't heard people use this before, even in other series/movies. Can someone please explain it to me or provide a link that defines this vocal gesture? Does it have an onomatopoeia? Is it different than the much more common "mm-hmm"?
