I'm pretty sure it's just a joke. Like, for example, a bunch of people in the fandoms for the TV shows "Steven Universe" and "Gravity Falls" will call the characters Peridot and Bill Cipher "doritos" because they're triangular. They do the same kind of things being done with Undyne such as calling them the nickname or messing with the wiki. It's all a big joke, and I can't really imagine anyone looking for information would actually take it seriously beacause, as you said, there's absolutely no in-game evidence to support she's a real pirate.
