back passage
Rear digestive exit
Back passage is a British euphemism for the rectum or anus, used especially in medical contexts or polite conversation to avoid more clinical or vulgar terms: The suppository is inserted into the back passage.
The phrase also has a literal meaning—a rear corridor or alleyway in a building.
