The word Shit is used in many different contexts. Observe:
1. When you recall something you haven't done, eg. Geography homework; it's like "Oh shit!"
2. When you hurt yourself rather stupidly eg. *kicks brick* "Argh... shiiittt!"
3. Laughingly. When someone does something really retarded, eg. *watches friend dive into the paddling pool* "Ahaha shit!"

4. When annoyed by something which is gross or wasting time, or quite literally, shit, eg. *dog has just crapped all over the floor* "Uh, shit!?"
5. When you are really, really riled about something and there is no-one to blame or vent on. "ARGH SHITTT!"
6. Said rather sarcastically or ironically, eg. *laughs with mates, saying "I probs got like 2% on that test!" thinking "yeah right!" and you get it back and you actually did* "Oh shite..."

Shit is crap. Crap is poo. Poo is excretion. Excretion is in the loo. The loo is dirty. Dirty is messy. Messy means to have a mess. Mess needs cleaning up. Cleaning is very shitty. Shitty is the act of being shit.
"Oh shit!", "Oh shat!" and "Oh shite!" are all variants of explaining the shitness of the situation.
Person 1: "That homework was really shitty, I couldn't do it!"
Person 2: "Oh shit, I haven't done it!"
Person 1: "Aww shat, man."
Person 2: "SHIT YES! IT'S NOT IN FOR TODAY!"
Person 1: "YES! No shit, I just realised mine's at home!"
Person 2: "Oh shit, it IS in for today!"
Person 1: "................ OH SHIT!"

A word used to describe a negative situation
One fine summertime Sunday evening
Crenshaw Boulevard was in full swing
Perfect example of how looks can be deceiving
Rolled up to what I thought was a pretty young thing
Rollin in a purple samuri suzuki dookie braids was an aid to her sex appeal
Dude she was dope man real dope on the real
Well anyway I went toot toot she said hey a beep beep
The next day rolled down to the beach, deuce deep
Me and my new Crenshaw cutie
Coolin on the beach and now she's rubbin on my booty
Suck suck suckin on my neck like dracula
But it wasn't all that spectacular
Cuz everytime I tried to touch upon her tay-titty
She would be like quit b
Bitch was frontin but I didn't say nothin
Then all of the sudden after someone pushed the button
I got a funny feeling like something was real wrong
Looked at her shoes and her feets was real long
Then it hit me oh please god no
Don't let this ho turn out to be a john doe
He pulled a fast one on me yo
I guess that's one of those things that make you go: shit!

Oh shit, oh shit, oh shit, oh shit, oh shit, oh shit, oh shit, oh
Shit
Oh shit, oh shit, oh shit....
