Military trivia
Back before the Air Force was reorganized in the early 90s, there were three major commands: Military Air Command, Stratgeic Air Command, and Tactical Air Command. The Commander-in-Chief of each command was known, respectively, as CINC-MAC (pronounced "sink mack"), CINC-SAC ("sink sack"), and CINC-TAC ("sink tack").

Only the old fogeys use this term anymore, but military wives used to be called CINC-HOUSE.

:-D
