Jolly raunchy rapper
Play off of Jolly Rancher, which is, of course, a candy just like the previously mentioned Laffy Taffy. Chance is also saying that he’s a happy, sometimes raunchy rapper. Lastly, rapper could be replaced with its homophone “wrapper”, as Jolly Rancher candies come individually wrapped.
This could also be a reference to lean
“with jolly ranchers at the bottom” — A$AP Rocky (Kissin Pink)
