o shi- 

When something you don't realize is about to happen. And by the time you relaize it, it's too late.

It doesn't necessarily have to be fatal, because sometimes it is used in day-to-day instances

Man opens box, sees bomb:
"O SHI-"

Student1: *catches breathe* I can't believe I made it to the bus on time!
Student2: Where's your backpack?
Student1: O SHI-

You search "Where is Chuck Norris" on Google:
"O SHI-"
