Honestly , I didn’t know any of those words as the words are used by YOUNG ppl. So it’s literally slangs and I had to study about it. (Haha) it was really interesting for me to study what they mean. 1. 까빠 (or 가빠 ) : it means “ 까면서 빠지다 or 까가 빠를 만들다” and it’s their short form. In this case, 까다 means to point out someone’s problem or to kick out 빠지다 means to be in love. “빠” means a slang of the word, fans In conclusion, 까빠 ( 까면서 빠지다 ) means people(especially fans) who point out celebrities’ problems even if they like the celebrities. And they fall in love after scolding the celebrities. In other words, they hated but they become to love the celebrities. 2. N인지지 : n means numbers and 지지 is probably from the verb, 지지하다 which means to support E.g. there is an idol group that has 5 members but if you are n인지지 Then you mean you don’t like all the members you support only certain members no matter how many member the group has. TMI: n인지지”X” means a community that doesn’t accept people who don’t support all the members in a group .... LOL 3. 순덕 means “ 순수 “ + “ 덕후(=fans) “ , pure fans but it can mean in a negative way. People think someone who is 순덕 are too supportive for a idol group even if they have problems. They always cover them like “ That’s not the idol group’s fault blah blah” 4.진입장벽 : 진입 = access / 장벽 = barrier or wall So if someone says 진입장벽이 높다(high) 낮다(low) then it means it is hard or easy to access somewhere. LOL I hope it is helpful for you. Slang is slang so do not think many people know that :) Thank you
