Oh, I found many misspells at my previous answer..sorry... I am posting again. ------------------- As you know, expression in Korean can be various forms according to relation between a speaker and a listener. "최고다" (stem form, used for writing) "당신이 최고입니다" (the most formal, for public speech) "최고예요" (formal, a junior tell a senior) "너가 최고야" (between friends, a senior tell a junior) "너가 제일 잘 나가" / "너가 짱이야" You rock! (slang, informal, among youngsters and friends) I think you have already listened to 2NE1's song "내가 제일 잘 나가" (I am the best) Here is the link for the music video with English and romanization subtitles. https://youtu.be/HVaQuaPKWfE
