Someone who no longer wears a mask indoors for large gatherings. These people are not anti-maskers/anti-vaxxers and used to wear their masks. Due to unclear expectations set by the CDC, state governments, businesses, and peers, they no longer wear their mask.
I was going to go to a wedding this weekend, but I'm sure there will be a lot of Mouth-breathers at the event.

The Rat Mouth is a mostly noctournal mammal who will mate with anything with a pulse. It's natural habitat encompasses all local watering holes and consumes copious amounts of alcohol. They are often forced to habitually migrate from one hole to another due to Alligator Mouth (see definition below), slander and libel (grafitti) to others and other henious acts. The Rat Mouth will puff up and instigate then call in reinforcements and cowardly call the law when they can no longer handle difficult prey. It will have the law on speed dial and inform the activities of it's former watering hole. Extreme caution should be used if you encounter a Rat Mouth. Do not befriend it, it is parasitic in nature and when all resources are exhausted it will turn on you with the above traits.
