Chewin in the Chung

You know, it is difficult for anyone over 30 to keep up with changing slang terms and usage. I can still barely understand something like this:

What's the delio yo?

And I can only get that because of the internet. And it’s still stupid. Delio? For fuck’s sake.

Also, we are all aware to some extent of slang from generations past. Nobody uses “square”, ‘groovy” or “dig it” any more, but they linger in lexiconical half-life through old movies, music and TV shows.

But check this out. Slang from this century but before widespread mass media. Looks like it’s roughly from the same era as “Square” and “Hip”, but with some stuff I’ve never heard before:

dracula (n.)
something in a class by itself

How would you use this as a noun? I’m so dracula yo.
