That's mostly true, except memes are ideas, more specifically ideas that spread by being repeated or imitated.
I know the definition very well both reading and hearing Richard Dawkins who coined and defined the term, explaining what a meme really is. And the idea is that memes can spread and evolve a bit like genes, which could be said to have been the case here if the meme had been changed to use the drawing u/Appoxo made.

Edit:
Funny why I'm downvoted for describing what a meme actually is???
God people are either stupid or vengeful here!!
