I live in Florida and somehow picked up this phrase recently. I use it to mean "About what are you making such a fuss?" either because I can't understand what is the big deal or because I genuinely have little-to-no idea what the person is talking about.교수님 what은 전치사 about의 목적어역할 맞죠?ㅎ

Is it just that a word was dropped between "you" and "on" like "what are you carrying on about?" 교수님 that절은 보어절 맞는지요? 그리고 보어절 안에서 의미의 모순이 있는것 같은데 제 생각이 맞나요? 누락된것(was dropped)과 누락되지 않은것(carrying)을 전치사like를 기준으로 비교하는 것 같은데 의미가 안 맞는것 맞죠? 부탁드릴게요..
