This is the first time I've encountered the term. Had to search to find out WTF ...

I just googled based on your comment. I assumed this was just socks with programming jokes written on them, but appearently it is actually a term for knee-high socks https://knowyourmeme.com/memes/programming-socks

I certainly hadn't heard of this either.

I've never heard of this either and thought they were referring to a trend from 10 years ago with wearing brightly colored socks.
