Black holes warp the spacetime around them, so your idea of distance is isn't really valid. Also the idea of time is warped as well, so the black hole doesn't quite just pass through your leg as you expect.

Nor does the black hole "suck" anything in.

What would happen from your perspective if such a black hole were to pass you at high velocity would be the same as if you were to pass the black hole at high velocity. From your perspective, you would begin orbiting that object, carried along with it. So would all the matter near you. But it would be matter, not objects, as the tidal forces would spaghettify all objects very quickly.
