"Joon" - (you did) (you would) (you won't again) It's something you say when you
know for a fact someone did something, you know they wouldn't do it again, but knowing them you know they definitely would do this type of shit in the first place. They wouldn't dare do it again and that's fact.
Lowkey disrespectful but gets the
point across to the other person that they need to take it seriously.
Example 1: "I can't believe I got back with my ex after I said I'd forget about her. Now it's officially over..." "Bro, joon already just stick to what you were doing before and focus on yourself
man." Example 2: "Really
Jim, I can't stand this bullshit joon
got me pissed off now gtfo out of my face."
