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.
