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 term to only be used during the Zombie Apocalypse. It is used to inform someone that a zombie is attempting to sneak up on them by abbreviating, "ZOMBIE! OH MY GOD!"
"Oh my god you guys, I think we're finally safe.... that was a close..." "ZOMG!" *shotgun bang* "Whew. Thanks man, that was close."
