omigosh 

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.

Becca: Omigosh, Jen! Brad just waved at me!
Jen: No way! Omigosh, did you wave back?
Becca: Omigosh, yes!

Omgosh 

Similar to OMG (Oh my god!), but ending with a fashionable "osh" to imply "Oh my gosh!", which isn't "Oh my god!", which is important, if importance was the issue. Which it's not.

It's just short for "Oh my gosh!".

Omgosh that beast is hawt.

Omigosh 

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.

Ashley: Oooomigosh, did you see Josh in class earlier today?
Brittney: Omigosh yes! He was soooooooooooo hot!

omigosh 

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!
