What is Oxygen Magnesium?
1.
Abbreviated form is OMg. Originally created to make fun of people who say OMG, so instead you would say "oxygen magnesium!!"
Unfortunately, it was later discovered that it would actually be magnesium oxide (MgO) but the joke still stands.
Some girl: Look at her shoes, aren't they ugly??
You (overhearing the above): Oxygen magnesium!! That's horrible!!
