Here we are guys, the long-awaited thread is finally here Sorry in advance for the shitty definition, I tried my best
Brief intro : Korean beauty standards are simple : big eyes (aegyo sal), v shaped face, small defined (preferably pointy) nose and small lips. Physical appearance and media influence being very important, getting your face done became quite common in Korea. The most requested surgery procedures being double eyelids, v line and rhinoplasty.
Gangnam is a famous city known for having celebrities hanging out there but also for having tons of surgery clinics. There's also this saying that when you walk down Gangnam, you could swear you saw the same person walking past you ten times.
Anyway, people started to use the term "gangnam unnie" to refer to girls looking all the same after getting their surgery done.
Here are a few examples :
