unprecedented 

unprecedented — a word that used to mean a person, event, timing or situation — P.E.T.S. — that had never happened before.

Now in the 21st century in the post-Trump Presidential Era it means: P.E.T.S. that happen everyday.

In literature this is called “the reversal theme”.

Here are a few contemporary examples:

“bad” means “good”.

Example: Man, that’s a bad car.

“Nasty” means “amazing”
Example: Man, that bad was nasty!

“Unprecedented” means “daily” or “regularly”
Example: Donald Trump telling lies is unprecedented.

This is one way languages undergo transformation; and, there are many examples of this in American English.

Donald Trump telling lies is unprecedented.
