Doom Pussy

This term was originated during the Viet Nam war. The
"Doom" refers to Da Nang Officers' Open Mess. The pussy refers to the model of a cat which was kept on a mantel in the club. When nobody was killed during the day's missions, the cat was set to face outward. If a crew was killed, then the cat was set to face the wall.

Well, I was wondering about that.
