Blowing the Stink Off

What does Blowing the Stink Off mean?  "Blowing the stink off" basically means getting outside for some fresh air, especially if you've been stuck inside too long. It’s like shaking off that cooped-up, stale feeling. Someone might say, “Let’s go for a walk and blow the stink off,” just to mean they need to get out and clear their head or stretch their legs.
