Malcolm opens up chapter 4 with the paragraph below. Why might he choose to open it up this way?

From the text:

Shorty would take me to groovy, frantic scenes in different chicks' and cats' pads, where with the lights and juke down mellow, everybody blew gage and juiced back and jumped. I met chicks who were fine as May wine, and cats who were hip to all happenings.

That paragraph is deliberate, of course; it's just to display a bit more of the slang that was used by everyone I respected as "hip" in those days. And in no time at all, I was talking the slang like a lifelong hipster.
