Jitty rock is a slang term for crack-cocaine or sometimes just called crack. It is a slang term I learned from my boss. You can also call Easy Off cleaner Jitty rock since according to my boss it’s “better then the crack down in the city”
“What did I tell you last week? Use that fuckin Easy off to clean that shit. It’s better then crack from the city.” “Man I love me some of that Jitty rock from time to time”
