Maci is a stylized spelling of Macy, a French-origin surname-turned-given-name meaning "weapon," that saw a significant bump in human baby name charts following the Teen Mom reality show's Maci Bookout, who became one of the series' most visible cast members from 2009 onward. Pet registries tend to follow human naming trends with a short lag.
