Sung-Joon

"Sung-Joon" is a slang term for someone who purposefully irritates others whilst acting oblivious to his/her actions.

Person X posts a photoshopped picture of Y to irritate him/her

Y: "why did you do that?!"
X: "ha...what are you talking about?"
Y:"You know what I mean!...your such a Sung-Joon"

Another example:

Person X falsely claims to have beaten up person Y in a sad attempt to gain clout from his/her peers.

Y: "Why are you telling people that you beat me up?"
X: (Giggling)"because I did"
Y: "What are you on about? Your such an SJ!"

Sungjoon

A guy that you would not talk to since he will create a argument out of it and use it against you.

"Hey what do you think about this cup?"
"The cup's plain design is just so useless."
"Wait what?"
