It's a satire of young new yorkers and anime tropes. It's hard to get if you don't live in the bubble it's commentating on but as someone who lives in New York as is around art and culture I get it and I get the parodies. It's a very specific niche not everyone is gonna get the art and fashion references. But it is 100% a parody because I'm around people like this all the time.
For example Tavi Gevision who voices helena st tessero is actually a well know fashion blogger so it's funny to see her make jokes like "I'm done with fashion etc."
It's not a show suburban middle American it's a show for rich art fart kids in big cities
It's also a parody of anime tropes
Like there's an entire episode that is a parody of Ranma ½
The Damian Hurst skull in episode like 3 is a real thing, and there's another episode where a guy is holding Chanel no5 but the bottle says babylon 5 which is a old niche sci fi show.
Also Kaz wasn't meant to be like able either. As a whole it's a very niche absurdist humor like the vaping joke for example; it's a slightly campy parody that was lost on a lot of people becuase it doesn't beat you over the head with it's humor it was all subtle and niche.
There's lots of parodies and references in the show they're just super niche
