Secondhand Munchies
Also known as Environmental Food Munch, or Passive Munch. When non-munchers are exposed to secondhand munchies it is called "involuntary munching" or "passive munching." Non-munchers who inhale secondhand munchies take in Funyions and other tasty snacks just like munchers do. The more secondhand munchies you are exposed to, the higher the level of these harmful chemicals in your body.
