o OKz
A way to tell someone to shut up when they're being a pain or giving you a stupid answer. It came from the internet and is now used by everyone.
'O OKz! I'm trying to sleep and you're talking about your dog's haircut!'
'O OKz! You said your dog ate my homework and now you're bragging about it!'
'O OKz! You asked me for advice and then you ignored it!'
