👉 Eating fumes, also known as food odors or vomit smells, are unpleasant aromas that can waft from a person's mouth or clothing, often due to the decomposition of food, especially when it's rotting or has been exposed to bacteria. These odors can be a mix of sulfurous compounds, such as hydrogen sulfide, and other volatile organic compounds that give them their characteristic pungent and sometimes rotten or fishy scent. The intensity can vary widely depending on the type and amount of food, personal hygiene, and environmental factors. While often embarrassing, these fumes are usually temporary and dissipate once the food is digested or cleaned up.
