I never watched that film.
Also, why would you assume a food with a random ass name should be known by all people around the world when it's only local to America?
Sliders aren't local to America I've had sliders here in Australia too, it's just a fancy small burger basically. White Castle has been in a bunch of movies, TV shows, references in music etc. Just like I know what Taco Bell is but I don't think they have one here in Australia, but I know what it is because it's mentioned in movies (like Demolition Man), and on podcasts etc that I watch or have seen at some point.
