I distinctly remember ages ago that there used to be certain people that did the "big sigh" sound effect in the audience when this happened! Don't you all remember?
I heard a distinct grunt. I think it came from my ex-boyfriends' mother. She was always upset with me about something. I even sent her 2 dozen roses one time and she was still mad at me. I couldn't understand how she could keep holding a grudge against me and still have a good conscience. OPPS! I kind of got off subject there... sorry.
Yeah, a grunt.... Kind of like when you pull a hangnail... or make a big poop.
