Nah Oi
It’s like saying no, but even worse. You’re not just disagreeing, you’re basically screaming that you hate everything right now.
Nah Oi! This plan is the worst, I’m not doing it!
Nah Oi! I don’t want to go to the store, I want to stay home and eat pizza!
Nah Oi! This is the dumbest idea I’ve ever heard, I’m not even close to being okay with this!
