"숭구리당당 숭당당 수구수구당당 숭당당" It was the words of famous comedian(김정렬) in early 1990s.

It is a fad word which a comedian made up with a hilarious dance more than 2 decades ago. It doesn't mean anything but sounds funny and similar to 수리수리마수리 (abracadabra). You can see a video of the dance on Youtube (https://www.youtube.com/watch?v=TCJFZRiysiQ)
