Moroccan is a name newly minted by Mariah Carey and Nick Cannon for their newborn twin son. Meaning a person who lives in Morocco, Moroccan was used by the couple as a nod to the Moroccan Room in Carey's Manhattan apartment, where Cannon proposed to the singer. Place-name Morocco is another choice for either sex, as is music name Maraca.
Moroccan might be thought of as a boys' name purely by virtue of its having been used for their newborn son by Mariah Carey and Nick Cannon, who transformed this nationality into a first name. But given that they named Moroccan's sister Monroe, conventional gender identity is off the table, and Moroccan might just as easily be used for a girl, along with Morocco or Maraca.
