Morphology

diaper + butt

The meaning is directly and transparently built from 'diaper' (an absorbent garment) + 'butt' (buttocks): it describes the padded/rounded appearance of a bottom when wearing a diaper. This is a straightforward noun–noun descriptive compound following common compositional patterns, so a B1 learner who knows both words would readily infer the meaning.

Etymology

Diaper butt comes from the simple picture of a baby's bottom looking rounded and soft because of a diaper. The word butt here means 'child's bottom', so the phrase describes that padded, rounded look.
