>>60004121A pseud is someone who pretends that they're intelligent and hide it. Fauna doesn't hide her stupidity. She literally always says that she's not good enough at a lot of things, and she has been very vocal about her imposter syndrome.
Anytime she brings up scientific topics, she talks about how much she knows, and from where she read about it. It's not like she can be an expert at that, she doesn't need to be she's just making conversation. Fauna is terminally online like us, and always knows the popular memes and things. And it's what streamers do, talk about stuff.
