Flataus law, also known as the flatulence principle, refers to the humorous notion that whoever smelt it, dealt it. This comical phrase is often used in a playful exchange when someone passes gas or releases an unpleasant odor. While Flataus law may not have any official synonyms due to its uniqueness, it is often substituted with phrases like "whoever denied it, supplied it", "the one who smelt it, dealt it" or "he who detected it, projected it". These alternative expressions serve the same purpose as Flataus law, adding a touch of levity to an embarrassing, yet relatable, bodily function.
