It's something I'm trying to teach my 4 year old cousin not to do. I don't know if it's the open mouth or just the sound that it makes, but it's certainly very annoying.

This is really annoying sometimes.Eating with your mouth open also will cause indigestion and gas.There are worse things one can do,but noisy eating is definately a turn off.

In Japan it is polite to make slurping noises when eating your noodles...or so I was told, and so I slurped so enthusiastically that I ruined a good tie with soy sauce. On the other hand, come to think of it, I might have been the victim of a practical joke for the amusement of my Japanese colleagues, also a possibility, I suppose, to give them further giggles after watching me struggle with chopsticks and noodles.

This is annoying to me. Especially because I work hard to respect other people when I eat. I try to be as little rude as possible. My mama taught me some manners.

that can be annoying listening to noisy eaters. some are worse than others. I have felt like leaving the room with certain people who make every disgusting sound they can. eating with their mouth wide open. smacking loudly, slurping their drink and gulping loudly. I do not claim to be perfect, maybe with certain noisy foods I might make some noise as most people do, but some people are flat out pigs.

don't get this one.
