An acronym for "oh my fucking stars", OMFS is commonly uttered by buttpirates, furfaggots, and neckbearded basement-dwellers to express surprise.

The neckbearded may also use "OMFS" as an acronym for "oh my fucking science" or "oh my fucking Satan" because "stars" are perceived as insufficiently secular, despite the fact that neckbeards believe that our molecules came from exploding stars, and that monkeys and fish fucked each other to create yo bitchass.

Although "OMFS" is generally used to express surprise, atheists also use it to express their hatred of christfags and our lord and savior, Jesus Christ. Of Nazareth.

Yes, that Jesus Christ.
OMFS! Let's have teh gay buttsects!

OMFS! Did you see that furry's throbbing, black furcock?!
