The dihydrogen monoxide parody involves calling water by the unfamiliar chemical name "dihydrogen monoxide" (DHMO), or "hydroxylic acid" in some cases, and listing some of water's well-known effects in a particularly alarming manner, such as accelerating corrosion and causing suffocation. The parody often calls for dihydrogen monoxide to be banned, regulated, or labeled as dangerous. It illustrates how a lack of scientific literacy and an exaggerated analysis can lead to misplaced fears.
