in spanish it's "¡oh, dios mio!" or you could try an even funnier way: "¡ay, diosito!"

As Italian Blonde already wrote, it's "Oh mio Dio" in Italian; however I find more frequently "Oddio" (the phonetic transcription of "Oh Dio", that is literally "Oh God").

In Turkish : Aman Allahım / Aman Tanrım / Aman Yarabbim.

in chinese, we say: "哦，我的天呐！" or “哦，我的老天爷！" or "我的妈呀！" in chinese, we say: "oh,wo de tian na ! " or "oh, wo de lao tian ye ! " or " wo de ma ya ! "
