The DK'ers,
The DKer's,
The DKers,
The Dkers,
The Deekairs

You may wonder which spelling is correct. I would say right off the bat that the ones with apostrophes are the worst. It is not suppose to be some kind of contraction, and the s is to make it plural not to show possession. Let's get rid of the unnecessary apostrophes. That leaves us with two options, the DKers and the Dkers.
