The equivalent of omigod or oh my god or oh my gosh usually said by ditzy girls that just slur the three words. Hence, omigosh, instead of oh my gosh.

See omigod. Much like oh my gosh, this is a shortened, valleygirl way of saying it. It's also relatively like oh my god, but substituting gosh for god, and deleting a few "spare letters". Can also be shortened to omg, or having a useless "z" added to make omgz.
omigosh, you're so illiterate!

How really {girly american girls say omg or oh my god/gosh. Add O's in the beginning to make it even more girly, and combine with even more O's in the word "so" to maximise the whole meaning of it.
