O shii
You shout O shii like you're about to die from embarrassment. It’s used when you see something so embarrassing or so awesome it makes your face turn red.
O shii! My brother tried to sing in the shower and it was like a horror movie.
O shii! My teacher made me wear a hat that said 'I love math' and it was so embarrassing.
O shii! My friend got a pet robot and it dances to my favorite song.
