I'm more confused now. What do you mean by dukes? Is the joke related to the weird shoes with open toes that for some reason have shoelaces when they don't need any?
It's an 80s era pop culture reference.
There was a character on the tv show, the Dukes of Hazard, named Daisy Duke.
She was known for wearing very tight fitting, cut off jean shorts.
That type of shorts became known as "daisy dukes", and was later popularized again in a hip-hop song.
The image in the post, if you aren't looking at it right, looks like a nice ass in those kind of shorts.
