I'd like to clarify the word "sexy" in the context of the Korean language/culture.
Yes, when you go to the Korean dictionary and search up the term, you'll get the definition "sexual attraction".
However, the term is commonly used among Koreans outside of its literal definition
또또 외국인들이 한국의 언어와 문화를 아예 이해할려고 하지도 않고 그저 누군가를 억까할려고 헛소문 퍼트리는거 지겹다
