Coming from starcraft where people used to say ''Zergling rush omg!'' and turned into ZOMG because people are just really really lazy.

Get the zomgmug. 
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."

Get the zomgmug. A variation of OMG. The 'Z' stands for "zombies". Thus ZOMG is an expression of shock used when one sees a lot of zombies.

Get the ZOMGmug. The Word Zomg Originates from OMG, Which means Oh my God, Or Oh My Gosh. The 'Z' in Zomg doesn't stand for anything at all.
