"Subway smell" is the staunch odor that soaks into your clothing while eating at a Subway restaurant. Many scientists theorize that this God awful smell is produced by the "fresh" baked bread; however, another competing school of thought theorizes that the stench comes from the chemical preservative liquid that the meats come packed in.
Once the smell has penetrated your clothing, you will inevitably smell like a rotten butthole for the rest of the day. Most people will mistake your newly acquired smell for B.O. unless you are carrying a Subway bag, in which case they will immediately understand the source of the offending odor.
