Millennials overuse the word "awesome". It's like the one thing they/we say.

This pizza is awesome. That song is awesome, etc. It totally devalues the word and renders it meaningless.

Gen Z has retarded ebonics slang, like "no cap", "bussin" fr fr", etc.

It should be obvious why that's bad.

Do your part and start incorporating words like rad and groovy into your speech. Tubular is too of it's time and people wouldn't take it seriously. But casually using rad and groovy would become accepted I believe.

We've lost the latitude of language we had in the 90s and earlier to describe things.

Instead, black slang started dominating in the 2000s and has only gotten worse.

Now the only word that isn't ghetto slang that people use is "awesome" or "cool".

Also don't use it in a hipster or ironic way. Just use it like you would normally and people will get used to it.
