I have never come across the term before, but Zydeco dancing seems to be a fun thing to do 
There is a huge web page about this cajun dance. If any of you know more please post and/or link to sites in the comments!
I am headed to New Orleans in a couple of weeks so I will let you know how it sounds live. I also am planning to Tango & Salsa while I am there. Can’t wait!
