The word 'belch' means to expel air loudly from your stomach through your mouth, often with a sound or an unpleasant odor. It is considered impolite to belch in public, especially during a meal or conversation. However, it is normal to belch after drinking soda, beer or eating certain foods. It is best to cover your mouth with your hand when belching and excuse yourself if in a formal setting.
