Hang on...

it's the axis of disc rotation, no? So, the axis in question is perp to the disc, through the center of the disc. Torque is force applied in a circular motion perpendicular to an axis.

So off-axis torque means that part of the rotational force you put on the disc is NOT perpendicular to the axis of the disc, regardless of how your body's leaning.

If this isn't right, then I'm banning myself from this thread, to avoid confusion.
