O que significa "unskinny bop"?

The meaning of "Unskinny Bop" has always been shrouded in obscurity. C.C. DeVille later confessed that the phrase "unskinny bop" has no particular meaning. He invented it as a temporary measure while writing the song, before vocalist Bret Michaels had begun working on the lyrics. The phrase was used on the basis that it was phonetically suited to the music. The song was later played to producer Fairbairn, who stated that, although he did not know what an "unskinny bop" was, the phrase was perfect. - en.wikipedia
