What does bebopulation mean?

It’s a word that I first heard in the song “Why Should I Worry? by Billy Joel from DIsney’s Oliver and Company and I was just wondering, what does it mean?

bebop is an old rock and roll term (“bebopalula she’s my baby” ), and I assume this word is derived from it; and Wikipedia says it originated in jazz much earlier

I couldn’t find it on merriam webster…maybe he made it up??? did you spell it right???

Sorry I couldn’t help…..
