用法筆記
In general conversation, native speakers rarely use evacuation for this sense — they prefer bowel movement or the informal poo (children) or BM. Use evacuation primarily in medical chart notes, clinical discussions, and patient questionnaires where a neutral, formal term is needed. The verb evacuate is even rarer in this sense outside hospital settings.
