adjective used to describe a person, place or thing which is questionable, fucked up, wrong, strange, broken down, undesirable, and/or just some thing you can't think of another word for. The origin of this work is explained somewhat in the conversation example. Friends and I were sitting around drinking coffee one morning, and I was bitching about my empty cup when my friend blamed the lack of coffee on the "janky ass coffee maker." I have since heard the word in the movie Friday.
Other forms: janked, janked up, janked out,
I was dancing with my friends and some janky old mutherfucker came up to me and started grabbin' my ass!
Michelle: yo, when's that coffee going to be ready?
Crystal: I don't know. This janky ass coffee maker takes forever.
He was a weirdo and made me feel all janked out, so I left.
I didn't get into Harvard. I don't know what I'm going to do now - it's totally janked up.
