That doesn’t match up with what KnowYourMeme.com says
Memes are broadly defined as culturally transmitted information or ideas and beliefs that can be spread from one organism, or group of organisms, to another.
Is know your meme composed primarily of twitter screenshots? Last time I checked the answer was no
It has a fair share of copypasta, and I am curious what would make copypasta a meme, but not a twitter screenshot.
