Mary. Madonna. Matriarch. Mamá. Mother. It’s an endearing term colloquially used to refer to a female figure who brings forth new life. But the word—which has been adopted by Gen Z and others who are up-to-date with internet jargon—is also a slang term that has been bestowed upon the biggest names in show business, be it Ariana Grande, Beyoncé, or Zendaya.
