Is a mitered corner end or side

Well, actually, it's neither. It's a mix of longer and shorter grain fibers behind the cut surface. That's why some reinforcement is often called for or using interlocking cut profiles.

It can be a SDJ

Self destruct Joint if it is flat and the boards wide. Any moisture content change in the wood may break the glueline. If the ends are prevented from moving, any loss of moisture causes the joint to break from the heel side, and conversely if the wood gains moisture, the swelling will break from the toe or outside corner back.

It's somewhere in between, and it may vary with the size of the pores. Basically, an endgrain joint would be like gluing two bundles of soda straws end to end; very little actual contact between tissue. The angle cut allows more contact, but the joint should be reinforced with splines, biscuits or tenons to add mechanical strength. I usually rub the first thin coat of glue into the mitered surfaces and let it tack briefly before adding more glue and clamping the joint together. This allows the glue to bind to a more continuous surface for greater adhesive strength.
