Perfect Duluth Day

Are you talkin’ it off or walkin’ it off?

So, I’m walking down East Third Street, minding my own business, and a middle-aged man with a goofy smile on his face asks me: “Are you talkin’ it off or walkin’ it off?”

Is that some kind of expression? What could it possibly mean? Did I hear him right?

I’ve found that it’s best in these situations to just say something quickly and politely while continuing to walk, so I just said, “Walking it off,” and kept going.

But now that interaction is bugging me. The only implication I can think of is that maybe I’m supposed to be walking off a hangover, which I guess sort of makes sense. But how would somebody talk off a hangover? And since I wasn’t talking, shouldn’t it have been obvious I was walking it off?
