I can't use it 'cause I'm a white boy, but I love unironic jive talk. A while back, I was watching a documentary about the black panthers and I think that was the first time I'd heard real people talking like that. Dudes were cool.
I'm in my 40s. At a family reunion my boomer uncle was super into my usage of "dope". I had to explain to him that this isn't cutting edge, it's 30 years old.
