Explanation
In the United States, slurping noodles is widely regarded as bad table manners because it produces loud, disruptive sounds that are associated with a lack of self-control and respect for fellow diners. American dining etiquette emphasizes quiet eating, and slurping is often seen as unrefined or even disgusting in most social settings.
