Although originating from a boys name, Petie is infact an affectionate name given to girls.

Peties are the brightest and happiest of people. These bubbly characters are a lot of fun to be around and the greatest people to have as friends. Loving and caring, a Petie will try and be there for you no mater what. You'll be lucky if you ever meet one as she'll always brighten your day <3
Person one: "isnt petie just the best?"
Person two: "yes she absolutely is! love that girl!"
