In programming, there are these so-called "esoteric programming languages" like "LOLCODE" or "Shakespeare," which really have pretty much zero usefulness. They are just kind of a novelty, or if a computer science professor is feeling like being particularly obnoxious he can choose it as the language for one of his assignments.
I was wondering if there is anything similar for citation styles. Citation styles are a "language" of sorts, and in principle you could have the analog of "LOLCODE" for making citations. I have never heard of such a thing, and I was considering inventing one---you know, something for a Humanities professor to require if they are feeling like being particularly obnoxious---but I wanted to make sure that such a thing didn't already exist.
