An alternate version of 'OMG'
Pronounced 'oh-am-nay-gee!', it's a short for 'Oh My Non-Existent God,' instead of the usual 'Oh My God!'
If you don't believe in God, use this instead of OMG.
Abbreviation for Oh My Fred and George. Predominantly used by fans of J.K.Rowling's bestseller series Harry Potter, it is a censored version of OMFG that is used to express approval or awesomeness.
