Jk: Jimin, why are you so small?
Jm: Excujjimi?
Jk: No offense, Jim.
Jm: Yah, call me hyung!
Jk: But I'm bigger.
Jm: I'm older!
Jk: I'm the top and you're the bottom, so I don't think it's right to call you hyung.
Jm:......
Listen up, buttercup. This joke is all about that top/bottom dynamic in a relationship. JK is being sassy, refusing to call Jimin "hyung" (which is what you call older bros in Korean) because he sees himself as the dominant one. It's like saying, "I'm in charge, so age ain't nothin' but a number!" You probably don't know anything about Korean honorifics because you write fan fiction. Stay cringe, my friend.
