A boi-o is a close friend that is down with all the memes and is kind of a hypebeast

A good way to greet them is to say,"Hoi o , boi-o."

Me: Hoi o, boi-o
Friend: "what's up my guy, I just got back from the supreme store."
Me: lit
"Wat's popping boi-o."
"Nothing much, I just copped that new supreme Tee though."
