dihydrogen monoxide

Dihydrogen Monoxide (DHMO) is a colorless and odorless chemical compound, also referred to by some as Dihydrogen Oxide, Hydrogen Hydroxide, Hydronium Hydroxide, or simply Hydric acid. Its basis is the unstable radical Hydroxide, the components of which are found in a number of caustic, explosive and poisonous compounds such as Sulfuric Acid, Nitroglycerine and Ethyl Alcohol.
For more detailed information, including precautions, disposal procedures and storage requirements, refer to the Material Safety Data Sheet (MSDS) for Dihydrogen Monoxide.
...Dihydrogen monoxide is water/H20.

Dihydrogen Monoxide as a toxic or carcinogenic substance (as it does with better known chemicals such as hydrochloric acid and saccharine), DHMO is a constituent of many known toxic substances, diseases and disease-causing agents, environmental hazards and can even be lethal to humans in quantities as small as a thimbleful.

Evidently really baaaad stuff.

In today's lab, you're gonna be working with dihydrogen monoxide. Now in large amounts, it could cause suffocation and death. If the subtance is heated, it could cause severe burns. Cold versions of this substance can also cause frostbite. Handle this lab with extreme caution, please.

Dihydrogen Monoxide

Sometimes shortened to DHMO or {H2O, it is the molecular name for water. For more information about chemistry, go to a science website. For more information about water, visit your local water bottle

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

A dangerous substance that can cause corrosion, suffocation, and many other life-threatening problems. Worse yet, it is found all over the world, and people often consume it without realizing it.

...Water. It's water. Did you get worried for a second? Congratulations: You have become a victim of Zohnerism; the use of a true (though confusing) statement that the general public would not be able to fully understand, causing them to jump to incorrect conclusions.

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.

Dihydrogen Oxide

Also known as "Dihydrogen Monoxide." A term for water that vax pushers and other science fanatics use to mock those who like organic food and choose to live naturally without harmful chemicals.

Michael saw the organix booth and was shouted "dihydrogen oxide OMGOMG! LOL!" then got his head stomped on the pavement. Michael now has medical bills he can't pay.
