9. “You are the best” (Oppaga choegoya)

In Korean (Hangeul): 오빠가 최고야
How to pronounce: oppa-ga chweh-go-ya

“Chweh-go” can be used for a myriad of situations, such as when you want to cheer someone on, or to describe someone or something as being the best. Give oppa two thumbs up while telling him he is the best – that’s bound to make him the envy of his group.
