An intentional misspelling of “omg” to mock the
idiots who abbreviate beyond reason. The phrase was created by citrus
child, who uses it to indicate shock,
happiness, dissatisfaction, and the like.
Gammy: I love you, wyfey
Citrus
child: MOG!
It can also be used to describe something.
Gammy: Too much caffeine, I can’t
sleep.
Citrus
child: sleep is mogging lame anyways.
