Have you heard this???
“Mom” is used as a term of praise by young fans in the US for people like a Supreme Court Justice: a “Jezebel” website headline demanded, “You leave our mom Ruth Bader Ginsburg alone, you monster,” and singer Beyoncé’s fans declared that she is “everyone’s mom.” [i]Singer Taylor Swift is also called “mom,” although she doesn’t have children. Female roommates sometimes call each other “mom.”
