I can definitively give the definition of the word janky since it was my friend who invented the word in 1990 in Chicago. It was originally used in a school project for a soap brand. The slogan was, "If you is stanky, use (you is) janky. It had a double meaning, firstlt to describe someone who is stinky (stanky) and secondly is was also the cure. We then started using the word the way you see it used today. To basically describe someone who is wack. "That fool is janky." or "That is one janky car." or "He tried to say that he was a good web designer but I took a look at some of his work and boy, was his shit JANKY." That's the long and short of it folks. Have fun with the word!!!!
