Memes don’t end at the image though. And by now, lots of memes are more than just images. If I say I’m going to “yeet” something, most people (below a certain age) know what that means. They don’t all become language, but the better, more popular ones do. It’s the same way we get all our words, really. I don’t know where the term “blue blooded” comes from, but I can still use it. In the same way, I don’t know where “down bad” came from, but I still know I’m down bad for etymology, and the study of evolutionary linguistics; it’s all fascinating.
