for anyone confused, they weren't laughing at the radio host's nose, they were actually laughing at the word "big nose" which means big d*ck in slang. you can even search up the clip of sehun in knowing bros, they were laughing at the same word. the radio host doesn't even have a big nose to start with so i'm 100% sure they weren't bullying anyone as y'all claimed them to be. also keep in mind that every country has their own slangs and jokes.
winter is literally me tho... if i find something funny, i won't stop laughing for five minutes cuz i'll just keep thinking about it and making myself laugh again and again-
BIG NOSE = EXCESSIVELY INTERESTED IN OTHERS PERSONAL MATTERS Thats what it means in slang, that's why they were laughing. Not cause of his actual nose.
To everyone who is saying that they are rude, probably didn't understand it. In Korea, it is common to say a man has a big "nose". (remember exo sehuns clip) So the way the comment was written was probably kinda like that. That's why they cracked up, because they didn't except such a comment. You can see how they tried to concentrate on the interview and to distract themselves of the thought. The DJ had a mask on, so they couldn't even see his face properly, so why should they laugh about it. That's why it was not the nose, but the other "nose" which was the reason they laughed.
