The entertainment industry is maintained by subsequent use of humors by entertainers. The use of humor by them is sometimes silly mode of making people laugh. It is widely held, when one is telling the silly speakings continually very long time, it is described in the single word “아무말” which is colloquial form of “아무런 말” which means “whatever non-meaningfully spoken” which is ridiculous look by any people.
At the Internet, some Youtubers make video that shows 아무말 speaking during the playback time, it is 아무말 대잔치, where 대잔치 is synonym to the meaning of festival or celebration ceremony.
The style of 아무말 is different by different people so it is not fed up and fun to watch. If someone adds clever use of thread of 아무말 spoken, it is sensational and becomes popular.
The translation would be: “the blah blah festival”.
