I wouldn't know ((anything) about that)

I wouldn't know ((anything) about that)

I have no knowledge or familiarity with what you are asking or discussing. Can be used glibly or sarcastically. A: "I absolutely love Barbados. It's one of the most beautiful places in the world!" B: "Hmm, I wouldn't know. I've never been able to afford a trip there." A: "I was wondering if you could help me. I need to fill out a form to have the deadline for my application extended." B: "I'm sorry, I wouldn't know anything about that." A: "Do you know how these drugs got here?" B: "No sir, officer, I wouldn't know about that."
