If the axis is the center of the discs spin, then it would be impossible, by definition, to apply off-axis torque by throwing a disc. OAT must then refer to being off of the 'axis of radial symmetry' of the disc, not the axis of rotation (which depends on that particular throw). After all, the axis of rotation is exactly what you just imparted to it.

For example, if you threw the disc so it toppled end-over-end like a flapjack.... If you put any of what we normally call spin on the disc also, then by your definition, that spin would be OAT since it's off the axis of rotation, which is end-over-end. However, in a regular throw, that same spin would not be OAT at all, when using the quoted definition.
