"Doahae" (도아해) is a recently coined term by a member South Korean boy group SEVENTEEN. Dokyeom (도겸) created this term as a contender to his bandmate's term, Horanghae. It is a combination of the
first syllable of Dokyeom's name, "도"/"Do", and "좋아해"/"Joahae", which means "I like you" in Korean. Although it's literal meaning is "I Do you", it is usually used in the place of saying that
one likes
something. It has been used by Dokyeom on his various Weverse posts and moments.
