This was a song released by the hair metal band, Poison, sometime in the late 80's or early 90's. It's a horrible song and nobody knows to this day what an "unskinny bop" is.
Scientists from Cal Tech and MIT have been trying to figure out the meaing of "Unskinny Bop" for over a decade. They have been unsuccessful so far.
