Proof that your mouth also dreams, mostly about garbage.
means The stale, sour-smelling breath you wake up with after hours of your mouth going dry and bacteria partying undisturbed overnight.
from Not an ancient word at all — just the plain English compound 'morning' + 'breath,' stitched together once people started talking casually about hygiene. The science behind it is older than the phrase: while you sleep, saliva production drops way down (saliva normally rinses away bacteria and food particles), so odor-causing bacteria in the mouth multiply freely for hours, producing sulfur compounds by sunrise. The phrase itself is a modern, everyday label for a very old biological fact.
- actual cause
- bacteria feast on dead cells overnight, unbothered
- saliva's job
- usually washes bacteria away, but sleep halts production
- mouth breathing
- dries saliva faster, upgrades breath from bad to nuclear
- fix that works
- tongue scraping beats mouthwash, which just masks it
