Meaning & Story
An Irish and Scottish surname, anglicization of Mac Caidhe or similar Gaelic forms. It became widely used through the expression the real McCoy, meaning the genuine article or the authentic thing.
Mccoy comes pre-loaded with one of the English language's great idioms: the real McCoy. Choosing this name is essentially declaring that your pet is the genuine article — no substitutes, no imitations, the authentic original. Star Trek fans will also think immediately of Dr. Leonard McCoy, the gruff but deeply compassionate ship's doctor. Either way, a pet named Mccoy tends to be exactly what it appears to be: real, warm, and entirely trustworthy.
