Passing gas, also known as farting, flatulence, flatus, or breaking wind, is a common bodily function that occurs when air is expelled from the digestive tract through the rectum. Other synonyms for the act of passing gas include tooting, trumping, blowing the horn, cutting the cheese, pulling a ripper, letting one go, and dropping a bomb. The sound and smell of gas can vary depending on a person's diet and lifestyle habits, but it is generally considered a natural and normal bodily process. While some cultures may find farting to be taboo or impolite, others may view it as harmless or even humorous.
