I must’ve been under a rock
So I was looking at some news website that was making me look at an ad before I even got to the first page. I happened to look at the URL and it had “prestitial” in the path.
“What?!” I thought. “That’s silly. Did they just make that up?”
Apparently they didn’t. Google tells us that the term has been in use for at least 2 years. It is an interesting extension of the language, though I’ll probably not use it ever again…
