放屁该怎么说英语

To say "fart" in English, you can simply say "fart." It is a noun that refers to the gas that is expelled from the digestive tract through the anus. You can also use the verb form, "to fart," which means to release gas from the digestive tract through the anus. For example, you can say "I farted" or "I need to fart." It is not considered polite to talk about farting in most social situations, so it is best to avoid discussing it unless it is necessary.
