wooahae (우아해) is a word used by SEVENTEEN's member-producer Woozi. Following the saga of fellow members Hoshi (horanghae) and DK (doahae), Woozi also created a term to express his love for Carats, wooahae. It is a combination of two words, one from the first syllable of Woozi's name (우; 'U' from Uji) and one from the Korean phrase "i love you" (saranghae). Its literal Korean translation is 'elegant' but Woozi does not mean that. He expresses wooahae just like how Hoshi and DK expresses theirs.
