An expression used by interweb-geeky people, the more interesting version of OMG.
ZOMG, there's an effing LLAMA in your anus.
Warning usually shouted when zombies approach
"ZOMG"
"WHAT?"
"OH SHIT ZOMBIES!!!"
Just another way to say, 'omg'.
Sally: Like my purse?
Jane: ZOMG! It's so cool!
Started randomly by me on a forum after wanting to have a signature phrase.
Only later did I realize it wasn't unique.
Now it's starting to actually being said aloud, pronounced "Zoh-My-Gosh".
Most people presume it's "God", but it diffrentiates ZOMG a bit more from OMG.
Paul: Zoh My Gosh! That girl's hot!
Zach: You're a nerd, you just said 'ZOMG!' out loud. You'll never get her.
Paul: Yeah...better go back to online dating.

A player who sees a unit of zurks in zurk formation nearing will say Zomg!
