Show the door means to dismiss, reject, expel, or force someone to leave. In poetry, the idiom turns social rejection into a physical gesture towards exit. It can appear in domestic quarrels, courtship, employment, political exile, or comic scenes of unwelcome guests. The door image suggests boundary, authority, and transition from belonging to exclusion. A poet may use it lightly or harshly, depending on whether dismissal is deserved, cruel, liberating, or final. It is useful for poems about thresholds.
