O shii
A loud and exaggerated way of saying oh shit. You scream the O like a squeaky toy and drag the shi out like you’re dying. Used when you see something so stupid or so amazing it makes your brain explode.
O shii! My neighbor tried to eat a whole pizza by himself and it looked like he was trying to swallow a raccoon.
O shii! My dog just pooped on my mom’s brand new shoes.
O shii! My teacher told me I have to do 100 push-ups for talking back to her.
