So, two things:
Since I don't have Twitter anymore, I don't have a place to drop short bon mots I think are clever -- if they're not clever, they're not bon mots.
Other thing, Kewl Term from the "It's a Thing" podcast, namely: Google-splaining. (Punctuation my own, choose your own.) Somewhat derived from the term man-splaining, which same term annoys the heck out of me. But I digress.
Basically, when someone did a Google search or two ("my own research") and then feels they can explain the details of something to everyone, including people who actually understand the subject, they're Google-splaining. They may have used any of the search engines, but it's Google-splaining.
I like the term for a number of reasons, especially that when you hear or see it you instantly know what it means.
