one who doesn't bother with looking for the proper spelling of words in the dictionary. Of course loooking up "dyslexia" or "dyslexic" in the dictionary, depending upon severity, could be an oxymoron. Which brings us back to JohnnyReno.
BTW-I was wondering. Why the moniker "johnnyreno"? But then I figured it out. Johnny comes from the slang for toilet, aka: john or head. While reno is a prefix for matters relating to the kidneys.

Draw your own conclusions, but for me, I think we should re-christen johnnyreno as Toilet Water, or stonehead, or beanhead.
