no siree Bob

informal "Siree" is an informal version of "sir" (sometimes spelled "sirree"), with "Bob" added for lighthearted emphasis. Primarily heard in US.

1. Absolutely not; no way. A: "I mean, would you betray your coworkers for a bit of extra money?" B: "No siree Bob—I have principles, thank you very much!"

2. Used to emphasize what one just said (rather than as a response to a question). We will not allow them to make a fool of us in court, no siree Bob!
