I think you are over thinking the entire scenario....
If I was in a certain setting and someone greeted me this way, I can relate, when I'm in the middle of a field in the middle of nowhere and the only spectators are groundhogs, I saw this greeting as ironic and cliche more than anything else...it goes to the old saying-adapt to where you are and act appropriately.....I for one would never, ever say "how's it going homie" to anyone the same as when I was in Australia I wasn't going around saying "G'day mate." because that's their thing.
And bear in mind, I was a no-nonsense, hardened soldier with more than a few overseas combat missions under my belt even at that time and was exposed to more than most.
And Yes, I don't like face piercings, ear stretching, crazy hair colors and painted fingernails on males....if someone has them, fine, that's their thing, I get that, it doesn't mean I have to like it and I would never go up to someone (normally) and tell them I don't like it...sometimes I'll even talk to them about it and ask a question such as 'do they sleep with them in, or did it hurt getting them (piercings)....I'm not an outdated Ogre afterall....(well maybe).
