The horrible, rancid taste that lodges itself in your mouth after working outside in traffic all day. It comes from all the exhaust that's inhaled all day long, which results in a nasty smell when you talk. Can only be beat with a toothbrush, strong gum or Altoids.
Oh man, riding around in between these buses has given me some nasty traffic breath!
