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-"

Used when something bad is about to happen, but you don't have time to finish what you were saying because it happens and you are either dead, or otherwise unable to finish what you were saying.

oshi 

A romanization of the Japanese word for “push” (推し). Among streaming communities, specifically Virtual Youtuber communities, it is used to refer to a streamer whom a person supports wholeheartedly, and in a manner greater than others within a particular industry or group. Reverence of said character can result in varying degrees of obsessiveness from occasional monetary donations to hoarding expensive merchandise

A: That is some really… interesting artwork you retweeted! I saw you had a pillow with that character on it, what anime is that?
B: That’s my oshi. He’s a wolf-boy mafia boss , and actually, he’s a VTuber from Holostars.

Oshi Hole 

A temple or alter built to honor your waifu/husbando, often in a closet. It is a hole in the wall where you can worship your oshi.

I stuffed my bodypillows of Aia Amare and Scarle Yonaguni, from Nijisanji EN, right into my oshi hole. Its a snug fit, but I can finally do my daily prayers while enveloped in their divine presence.
