A reader: “Mr. Derb—I happen to be a bond guy, so I understand ‘DK-ed,’
but I’d be curious as to how many of your readers inquire as to its meaning.
I remember being shocked the first time I heard my wife (a civilian) use the
phrase. The first time I ever heard it used in a bar was pretty good, too.
A friend of mine tried to pick up a young lady and failed. When he came
back to our table and was asked what happened, all he said was ‘She DK-ed
me.’ Perfect usage.”
For a definition of “DK-ed,” see here.
