freedom baggie
n. A one-quart, clear plastic bag into which you place your 100-mL bottles of liquids in order to carry them aboard an airplane. A magical device that somehow prevents you from blowing up a plane with solid explosives, or emptying all your little bottles into one big one. Security theater in action.
You can take away my Fourth Amendment right to be free of illegal search and seizure, but you'll never take away my freedom baggie.
