Here are some examples of how "fausty" is used:
* "That old book smells fausty."
* "The basement is fausty and damp."
* "The air in the room was fausty after the party."
The word "fausty" is likely a variant of the word "fusty," which has a similar meaning. However, "fausty" has a more specific Newfoundland flavour and is often used to describe a particularly unpleasant smell.
