A Polaroid is a material that aligns ordinary unpolarized light into a single plane. Crossed polaroids are simply two polaroids set up so that the second Polaroid is aligning the light into a plane perpendicular to the plane of the first. To put it more simply, the first Polaroid crams the light into the Y axis and the second crams the light along the Y axis into the X axis which essentially reduces it to nothing.

By definition: "The secondary focal point is where rays that are parallel when they enter the lens cross or appear to have crossed."
