Morphology
rear + back
The meaning is directly and transparently derived from combining 'rear' (to rise up on the hind legs) with 'back' (indicating a backward/directional movement or emphasis). The particle-like use of 'back' reinforces the motion and this verb + particle/directional pattern is common and predictable, so a B1 learner who knows both words would readily infer the MWE meaning.
Etymology
Rear back shows what a horse or other animal does when it suddenly lifts its front and moves backward; rear means to rise on the hind legs and back shows the backward motion. So it means 'to stand up on the hind legs'.
