Selective mutism 

A "rare" anxiety disorder that typically starts in childhood. It's main trait is being mute in public. But this trait can extend to nonverbal communication as well. Basically social anxiety on drugs.

Child: *has selective mutism*
Parents: Our kid is rude for not talking in public so instead of taking them to therapy let's leave them like this and continue to be upset at them because it must be a choice cause children LOVE not having friends! Lol!

Muskism 

A religion in which the followers worship the all mighty god and true daddy, Elon Musk (CEO of Tesla, SpaceX, and the Boring Company.) Followers are devoted and obsessed with the creations and actions of Elon and will do anything to help the earth become clean and humans become a multi-planetary species.

Dude 1: Dude I just converted to Muskism!
Dude 2: That's sick man I've been considering it for a while now.
Dude 1: You should totally do it, it's the best thing that's ever happened to me.
Dude 3: What the fuck is Muskism?
Dude 1: It's the all mighty religion. But I don't think your intellect is high enough to understand this.
