bag nasty
n.— «This might seem frivolous, but frankly, when you perpetuate terms like “chow hall” and “bag-nasty,” it shows no respect for the services professionals who bust their tails to make sure you don’t go hungry.» —“Air mail: Box nasties” by Owen Davies in Elmendorf Air Force Base, Alaska Airman Feb. 1, 2001.
