Except the bouba/kiki effect isn't a short lived meme. It's been studied (first as baluba/takete) since the 60s. And as long as there are linguists it will exist. 🤷🏼♀️
Huh. Kinda makes me wonder if you really understand it. Because there is all sorts of fascinating research stemming the effect. It isn't just a silly meme, it is a legitimate area of research.
