The name Buddy is a boy's name . Buddy and is often added to lists like Crazy Nicknames for Boys and discussed in our forums with posts like "Release the 20 T.I.G.E.R.S. -- the anti-elimination game! (BOYS)".
From the experts:
Very rarely used as a proper name; Buddy Holly, for example, was christened Charles, and Salinger's Buddy Glass was born Webb. Celebrity chef Jamie Oliver did name his fourth child Buddy Bear Maurice--a fittingly named brother to Poppy Honey Rosie, Daisy Boo Pamela and Petal Blossom Rainbow.
