JOI có nghĩa là

Hello. I just want to tell you that you're the fucking most stupid guy in the school, really.

I'm not sure if it's possible to be such a stupid asshole, but I want to notice that you're not just stupid, you're an ugly.

And I want to prove myself that you're ugly, stupid asshole and absolutely pathetic everywhere.

Close the door, lock it, take off your fucking pants and show me what dick do you have.

What dick do you have?
