no siree Bob

Absolutely, positively not

No siree Bob is an emphatic way of saying no, adding folksy emphasis to a refusal or denial: Are you going to let him talk to you that way? No siree Bob.

The Bob is meaningless—just a rhythmic addition like the similar yes siree Bob.

The expression sounds old-fashioned or deliberately corny, often used for humorous effect.
