A variation of oh my god, but with emphasis on breasts. Best efficient use of the word is when your in great shock.
I went into an elevator and met some women with very firm and nicely shaped breast. This type of situation just screams, Oh My TITS!!

Something you say when you're utterly surprised or when something unexpected come up. It is the best phrase when you can't believe something just happened or when there are no other words to describe something.
