 * 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.''

Personally, I just like using it sarcastically.
