Slang is much a part of the military as MREs, physical fitness tests, and shitty base housing. Each branch and unit has its own verbal shorthand, and Navy aviators are no exception — even though much of the colorful language deployed by pilots is a shorthand for expletives you can use over radio transmissions without getting slammed for misconduct.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
