So memes have always been a version of an “inside joke” you typically need prior knowledge of the source material in the meme to fully appreciate the joke. But these kinds of “memes” are just literal memory/ nostalgia pandering like the member-berries from South Park. There’s not actually a joke in any of these memes. The whole “joke” is “hey I’ve seen that thing”. Whereas normally the joke from a meme is something like “hey I’ve seen that thing, so I have context of the situation and now I must apply that context to another situation and find the humor”. These memes have none of that effort. They’re garbage. And 9/10 times it’s not even a “funny” thing getting memed.
