I read the headline as
Is Macy’s going to be doing c–nide in Maryland?
A c–nide is a chemical compound that contains the group C≡N. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. In inorganic c–nides, the c–nide group is present as the anion CN−. Salts such as sodium c–nide and potassium c–nide are highly toxic.
