H2O
(also H2O)
noun [mass noun] informal
Water (the chemical symbol, as used in non-scientific contexts): if you spend a leisurely ten minutes washing and rinsing, you’ll be going through gallons of H2O...
- The dishwasher was leaking all to hell and my kitchen was submersed in a good half an inch of concentrated soap and H20.
- Whether it's an extra 30 minutes of sleep a night, taking a trip, learning a foreign language, reading a book or snowboarding down the side of a mountain, be sure to drink plenty of H20 while pursuing fun activities.
- Also, your body will need more water as the mercury rises to stay hydrated, so if you were skimping on the H20 during the winter, make it a goal to drink the suggested eight glasses of water every day.
Origin
From H2, chemical symbol for hydrogen, + 2 + O2, chemical symbol for oxygen.
