OHMYBEEJEZUZ!
It's a more shocked way to say "OMG!" It adds more... phzazz to it.
You've just found out your adopted, and you really weren't paying attention, so you just start screaming "OHMYBEEJEZUZ!" Because you were far more intrested in the fly you were intent on killing that kept buzzing around your head.. Either that or you finally killed it and shouted "OHMYBEEJEZUZ I WIN!!" and then you find out several hours later, that your real name is "!XOBILE" and that your parents are immigrants from Africa..
