I think what I don't like most about people who use cringe as an adjective is how ungrammatical it sounds. Cring(e)y or cringeworthy would be better.
This is America. WE have the freedom to verb all nouns. No exceptions.In the 1990s, Bill Waterson famously said "verbing weirds language".
In the last decade, I've found adjectifying weirds conversations.
Must be a product of its times.
