I just ask a few of my friends how they think some fan bases call themself..

here are the results:

Rihanna - Navy
Katy Perry - Cats
Lady GaGa - Monsters
Beyonce - Destiny Child's
JLO - they had no idea
Shakira - Shaks
Ariana Grande - (they actually didn't know who she was)

They genuinely have no idea imo

I'm not even sure if they know most of those artists. We have different 'major' artists than in the U.S in my country (and I dislike them). Despite that, I have the most non musical people in my life and I feel like an alien. Somebody adopt me.
