어쩌고저쩌고 is a fixed pair meaning "this and that, blah blah" — it stands in for content the speaker cannot be bothered to repeat, usually with a shrug: MBTI 어쩌고저쩌고 말이야 "MBTI this, MBTI that". Every line here is that phrase, so learn it whole rather than splitting it into parts. One line pairs it with 이러쿵 저러쿵, its close synonym, and another adds 쫑알쫑알, the sound of someone chattering on.
