Is there anything I can do to seem clier or should I just go with the blue collar flow?

So 26, pretty good looking guy, I'm a mechanic/truck driver, smoke like a chimney, drink a lot, use tons of profanity, get high from time to time, super laid back. Got a couple of tattoos on my upper arms and one on my chest. I don't really have trouble getting chicks cuz I'm good looking, but I think people would think of me as more a fun guy to bullshit with or get wasted with but not that I have anything earth shatteringly intelligent going on upstairs. What say you?
