Could somone please explain to me the origin/meaning/joke behind this phrase? I’m seeing it all over the place.
Apologies if this is the wrong forum.
I think this is more of a MPSIMS kind of thing, so off it goes.
Im not sure where it came from, but the correct spelling is OHNOES 
The smilie is obligitory.
Apollo?
Okay, mebbe not.
When one Oh No! simply won’t do…
I always hear the voice of Mr. Bill (the claymation guy (from SNL I think) that always gets squished) when I read that. I don’t know if that’s where it comes from or not.
Taken from Urban Dictionary: Oh Noes

Yerp,
Thats what I got from “Oh Noes!” Explanation…
If everyone reads an unfortunate story at the end they would all yell… OH NO!
You would then be in the act of hearing a chorus of …OH NOES!
I think it’s pretty funny when a single person says, “Oh Noes!” when hearing bad news while with other people.
BOSS: You will all continue to work until I get tired! BWAH HA HA HA!
WORKER: (all the way at the back of the office) oh noes!!!
And upon waking up one morning and realising I had overslept I discovered that the phrase ‘Uh ohs!’ also has its uses. 
Again, because one ‘oh’ simply wasn’t enough.
I don’t know where it came from, but when I read it, I always hear it in Edie McClurg’s voice.
In the kids’ I Love Toy Trains videos, a growly-voiced guy says this every time a train falls off the track or goes crashing through a wall. “Oh no!” It’s become a catchphrase in our family.
