boi-o 

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."

Boi-oing

An expression used for stating sarcastic unamusement. Much like sarcastically saying "oh wow" or "big whoop". Used to mimick the comical sound of getting an instant erection, or boner one would get if something actually was enjoyable or cool. Used to blow someone off sarcastically.

Noah: Hey guess what? I finally was able to get married and laid in my video game Fable II.
