Abbreviation for "Oh my fucks!". Particularly used to replace "Oh my gosh" from "oh my god" when trying not to use the word "god", or having "gosh" mistaken for it. Can be used by either fundies or atheists, either not using "god" because it's a sin to use it in vain, or merely because you don't believe in theism and don't want to support it.
As an acronym it has become symbolic of AmericanPunk.
"That's more of what we do, It means OTHER MUSIC FOR UPLIFTING
GORMANDIZERS." And what is a gormandizer? It's a voracious eater of,
in this case, MUSIC."
