O shii
You scream O shii like you're being attacked by a swarm of bees. It’s used when you see something so ridiculous or so cool it makes your brain short circuit.
O shii! My teacher wore socks with flamingos on them to class today.
O shii! My cat just walked into a cake and it looked like a disaster.
O shii! My friend drew a picture of me with a mustache and it’s hilarious.
