I don't think it has much of a chance being widespread

I first heard of it back when Usenet was still the hotness.

Apparently it's been around for close to a century, so if it hasn't caught on widely by now, you're probably right.

> I first heard of it back when Usenet was still the hotness.

This is the first (and probably last) time that I will ever see the words "Usenet" and "hotness" in the same sentence.

Well done, sir.
