look up any word, like timebomb:
 
2.
An exclamation of surprise, excitement, sadness, or fear. Pretty much the wimpy way of saying "oh my god." usually used by strong christians or when in a group of christians and you just want to be safe and not offend anyone.
Sadness:
Person 1: I just saw a dead deer on the side of the road!
Person 2: Oh my gosh, that's so sad!

Exclamation:
Oh my gosh! I'm so excited to go to Emma's birthday party!

Surprise:
Oh my gosh, you scared me! I didn't see you standing there.

Fear:
Oh my gosh, what if my parents find out about me failing my math quiz?? Oh no!

Much like oh my god, or the shortened form omg, oh my gosh can also be condensed into omg, and thus people will have no idea whether you are talking about god or gosh. However, angry Christians who hate to use the Lord's name in vain, usually type oh my gosh online, rather than oh my god.
