NOTE: Being such a rare term, it is commonly used by 4Chan to prank people. A common prank is listed below.

Did you know that there is a substance called Dihydrogen Monoxide that causes a lot of death and disturbance every second? When you breathe DHMO, you die. But Big Pharma doesn't want you to know! Dihydrogen Monoxide is present in every single vaccine, and 100% of Autistic children have drunk it. Big Pharma has put DHMO in all your medicines, and even Homeopathy cannot exist without it. If you drink too much, you die. But yet, you are given DHMO at the doctor's office when you ask for water. SMH my head Big Pharma will never learn

Dihydrogen Monoxide is often used in April Fool's pranks to fool people who do not know what it is. It was popularized by then 14-year-old Nathan Zohmer, who trolled almost all of his ninth-grade classmates into banning it from the school he attended for a science fair.
