ZOMG is neither an acronym nor a word; it is an entity. ZOMG is a mythological figure who wields a sword tainted with the blood of emo kids.
Bill: Jesus Christ! That ZOMG just stabbed the lead singer of My Chemical Romance in the eye!
Bob: You're right! and now the bassist is crying!

zOMG is a varient of the all-too-popular acronym "OMG", meaning "Oh My God".

The "z" was originally a mistake while attempting to hit the shift key with the left hand, and type "OMG"

Also used in all-caps, 'ZOMG' is generally used in a sarcastic manner, more often than not a humiliating fasion. It is also used as a device for stating the obvious.
"zOMG! you r teh winz!!one!!eleven!"

A more enthusiastic (if not sarcastic) way of saying OMG. The Z doesn't stand for anything, but rather is added onto the O, thus making it pronounced "ZOH MY GOD!!1"

A variation of OMG. The Z doesn't stand for anything; the word was accidentally invented by users intending to hit the Shift Key instead of Z.

It was used by some gamers for a time in 2004. In 2006, its usage became widespread.

1. A variant of omg which means "oh my god". It first originated as an rare typo when someone says "OMG" in caps and presses the left shift key rather then the right and accidentally hits the near by Z.

It was picked up and used as a humorous way of saying omg and making fun of internet slang in general do to its funny pronunciation of "Zoh-my-God!".
