Do you, this poem, like?

I get the general idea, but one thing really floored me. We are living at the same time in the same country, and presumably speak the same language. But I've been a city boy all my life, and evidently you are from the suburbs or countryside. Yet it is amazing to me how many of the referents are unfamiliar. I think I figured out most of them, but..... what is a "puke?"
