Kkondae
Kkondae is an expression used in South Korea to describe a condescending person. The slang noun kkondae was originally used by students and teenagers to refer to older people such as fathers and teachers. Recently, however, the word has been used to refer to a boss or an older person who does so-called kkondae-jil, that forces the former's outdated way of thinking onto another person.
