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.

ZOMG is OMG with a sarcastic twist. Logan and Jacob were really tired and nothing made sense so they said ZOMG (a typo at the time) was OMG but sarcastic
