A DJ friend in Columbus Ohio coined the term "jenky," because he couldn't find another to describe how remixed music gets corrupted in quality, the beats don't match up, or the finished project ends up worse than the original. Contrast that with "wonky," where it was not quite right to begin with.
And it's not pop, soda, tonic, or coke. It's a frosty beverage, which can contain alcohol or not.
