I really want to coin a word or phrase, and if I can't make the OED, I am at least aiming for Urban Dictionary. So, drumroll please, here is a new term I made up that going to be so popular with the kids:

Main Entry: Whoa·M·G
Pronunciation: \whoa-ˈem-gee\
Function: exclamation
Etymology: IM speak, circa AOL
Date: 2010

1 a : Expression of shock, used when a simple "OMG" just won't get the job done.

ETA: Tori informs me that this is already in Urban Dictionary. Shoot! I swear I did not know, nor did I take the time to research this. Thanks for letting me know that my ideas are already in existence!
