As a perpetual "y'all" user from the American South, I hate how this term has pretty much been yanked (ahem) away from us by people who are nothing like us.
It's a real word that's been around for a while, like "That made me cringe" or something. But it's a very modern thing to hear it as a one-word reaction to something ("Cringe!") or used as an adjective ("That show is cringe") rather than its proper form as a verb.
It's modern usage also tends to be used as one of those catch-all word-that-describes-something-not-good too.
