The fear or idea that wearing a mask in public for long periods of time will cause grave illness or death. This is common within the Karen and Chad communities and quite often reflected in Twitter or Facebook rants. The individual is often seen healthy and fine in public wearing a mask though.
Karen loves to make videos in her car after shopping at HomeGoods saying how she feels nauseous, weak and is having heart palpitations from wearing her mask. She is suffering from an extreme case of maskochondria.
