Here's one that requires a little bit of background explanation. During combat missions time is a critical factor so every aircraft in the Air Force has at least one clock installed in the cockpit. Even though we live in the modern era these clocks are mechanical, they need to be wound. Most pilots aren't aware of this requirement so us maintenance toads see "clock inoperative" write-ups quite often. One night I was in a punchy mood and tired of just saying "wound clock" so this night I signed off the write-up as, "Adjusted mainspring mechanism to proper torque value." The storm of controversy that followed was intense. It's scary how many supposedly educated people have a piss poor vocabulary.
