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.
It comes out of music. The "groove" of a song, particular jazz, is kind of the rhythm, the feel, the overall impact. You can say "Wow, that drummer is really grooving!" If he's really into the song, really driving, really fitting in. Colloquially, if you're "in the groove" you're doing great, really nailing whatever task you're on, etc.
"I'm in the groove! I just coded a new hit box algorithm I've been stuck on for days!"
"Groovy" really just means "Cool." Often used in a kind of arts or music of visual context. Today mostly used ironically. It's old slang. If I saw a kid wearing some really funky tyedyed shirt or something I might say "Hey, that's a pretty groovy shirt!"
Does Duke Nukem or Doom Guy say "Groovy" at some point??
Ash from Evil Dead does.
Yes, that's who got me started saying it. Also BITCHIN. Later I learned that all his lines were lifted from other pop culture references, but he's still my number one male role model.
Now there is a word we should bring back. Rad is seen as too lame, but 'bitchin'' will annoy all the right people, then try to be reclaimed.
It could do real numbers.
