I say this as a person who prefers to speak as frankly and casually as the author does, but when going into broadcast mode it's worthwhile to ask yourself if your language supports your mission or not (for instance, by pre-empting the majority of the comments in post that are curious about the language choice).

To me, the “tech person gives advice while brazenly cursing to show how serious and authoritative they are” is a meme.

Edit: I just learned that “cringey” is not In most dictionaries yet (which explains why spell check is saying it’s not a word). That said, the term fills a void where no other term conveniently comes to mind.
