There are various euphemisms for the term "pass gas," which is commonly used to describe the act of releasing gas from the body through the rectum. Some people may say "toot," "fart," "break wind," "cut the cheese," "let one rip," or "fartlek." Each of these expressions is used to describe the same action, but some are more formal than others. While it is generally considered impolite to speak openly about flatulence, it is also considered impolite to use crude language. Therefore, using a euphemism can be a polite way to communicate the act of farting.
