1.
to feel ashamed, embarrassed, or awkward
Describes feeling uncomfortable or unable to hold one's head high, often due to circumstances beyond one's control or the actions of someone close.
Structure: 肩身 (one's standing/position, literally 'shoulder-body') + が + 狭い (narrow). The image is of hunching one's shoulders to take up less space.
Nuance: Often used when one feels embarrassed due to external circumstances (family member's actions, social status) rather than one's own direct wrongdoing. Implies a social dimension - feeling judged by others.
Antonym: 肩身が広い (to feel proud, hold one's head high)
