I wouldn't say it's exactly "buzzwords", although their presence can be one signal out of many, but a particular style and word choice that makes it easy to detect AI-generated text.

Imagine the most vapid, average, NPC-ish corporate drone that writes in an overly positive tone with fake cheerfulness and excessive verboseness. That's what AI evokes to me.

The opposite is someone who is trying to tell you something but assumes you already know what they're trying to tell you and that you will ask questions if you don't understand.

It saves time but it means people have to say when they don't understand and some find that too much of a challenge.
