1. slang Obviously; that is or was completely self-evident. "Shinola," the name of a brand of (usually black or brown) shoe polish, is used as a substitute for the vulgar term "shit." A: "I think we need to clear that blockage out of the drain." B: "Yeah, no Shinola. Thanks for the tip."
2. slang Are you being serious? Wow, is that really true? A: "My aunt has a cabin we could use for the weekend." B: "No Shinola? That would be awesome!"
exclam. You are kidding!; No shit! (A play on the expression indicating that a stupid person doesn’t know shit from Shinola. Shinola is a brand of shoe polish.) So taxes are too high? No Shinola!
