This sort of half-assed mumbling they do is their way of withholding their full participation and thus “dissing” the “Man.” It’s a fairly prominent component of New Cracker Speak to speak softly and mumble. See, they are actually larvae. They are not fully formed so they can’t just stand up and say what they mean or don’t mean. They feel safer remaining under the surface like maggots, feeling that if they are exposed, they will be eaten or sprayed with insecticide or washed away in a torrent of Clorox and water. It doesn’t occur to them that if they were to quit being maggots and be real people, nobody would particularly want to get rid of them.
