At my partner's house, there are two cats: Mr. And Mrs. Rizzler. The teenagers in the house started calling them that and everyone went with it. Before then, the term was used basically every single time I saw any of them. It seems to most often be used as nonsense or just a word to shout at each other while trying to be annoying, but sometimes in the actual context of charisma (for example, a charismatic classmate was described as a "rizzler").

So yeah, it's a thing in some circles, but I'm hopeful this is an isolated incident.
