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.

[Couch Potatoe]

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

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!.

zombies! oh my god!

[Sarah]

A very alternative definition is Zombies, oh my God when youre surprised by zombies. Also works with zebras and xylophones, because when someone is surprised by a pack of xylophones they often forget how to spell it.

[Raeanne Dimick]

an extremely pointless phrase, created by a typo. while trying to reach the shift key and type [OMG], the z was typed.
many people enjoy making fun of this phrase.
